This will work great with my old Yakima rocket box with round bars. My new Subaru Forester has 3" crossbars and these brackets will work. Great phone in service before I ordered.. They took extra time to give me the best brackets to order. 311791

The Replacement Mounting Hardware Kit (8870098) was just what I needed to get an older model Yakima RocketBox to mount on my Toyota Highlander. The order arrived on time and included everything listed on the product page. I would highly recommend using etrailer.com for any of your trailer needs. 420943

Thank you for being so helpful. Finding the right parts to attach our 20 year old Space Case to the next generations truck was daunting. Everything was no longer manufactured. But you had the work around solution immediately. We ordered over the phone mid-afternoon from home in California and it arrived at our front door the next morning. How did you do that? You deserve 10 stars. 850874

  • Replacement Mounting Hardware Options for Older Yakima SpaceCase Cargo Box
    The correct replacement mounting hardware available for the Yakima SpaceCase Cargo Box is the Replacement Mounting Hardware part # 8870098. The Replacement Quick-Dial Mounting Assembly part # Y8870097 will not work as it requires a rather unique channel which would be very hard to replicate when retrofitting. If you are looking for an easier to use option, the Replacement QM3 Hardware part # TH04997 are much more universal and will work well with the Yakima SpaceCase Cargo Box but drilling...

  • Replacement Mounting Hardware for the Yakima SpaceCase Cargo Box
    The correct replacement mounting hardware for the Yakima SpaceCase is the Replacement Mounting Hardware Kit part # 8870098. I spoke with Yakima and they stated that this is the only type of mounting hardware that will work as there is no upgraded option for this like the Replacement Mounting Hardware part # Y8870084 unfortunately.

  • How To Mount Older Yakima RocketBox on a Honda Odyssey Factory Roof Rack
    The Replacement Mounting Hardware part # 8870098 will work with older Yakima RocketBoxes and fit factory crossbars up to 3-7/8" wide x 1-1/2" tall. As you mentioned, drilling most likely will be needed as the above kit is a universal mounting kit that may require certain modifications such as drilling holes in able to accommodate certain cargo boxes. If the factory crossbars are larger than 3-7/8" wide x 1-1/2" tall please let me know and I will see if there are other options.

  • Replacement Mounting Hardware Needed for Old Driverside Yakima RocketBox 8007102
    The correct replacement mounting hardware for your driverside RocketBox 8007102 (thanks for the part number by the way) is the kit # 8870098. I confirmed this with Yakima directly. The Mounting Hardware # Y8870084 could possibly work if you're willing to modify your box (as you've seen done by other customers on that product page), but you won't be able to get the sliding action that this hardware normally gives simply because your box doesn't have the tracks for it.

  • Replacement Mounting Hardware for Yakima RocketBox on 2000 Chevy Astro with Factory Crossbars
    The correct mounting hardware for your older Yakima RocketBox is the Replacement Mounting Hardware # 8870098. The U-bolts in this kit will work with any crossbars that are under 3-7/8 inches wide and under 1-1/2 inches tall. This includes the 2 inch wide factory crossbars on your 2000 Chevy Astro. In addition to the 4 U-bolts, this kit also includes the needed 4 plates and 8 knobs. The U-bolts themselves measure 4-1/4 inches long center to center and have 1-1/2 inches of thread.

  • Is Yakima Replacement Mounting Hardware # Y8870084 Compatible with Aero Crossbars
    I spoke with my contact at Yakima and he stated that the Replacement Mounting Hardware # Y8870084 is indeed compatible with aero-style crossbars including your AeroBlade models. You will just want to make sure that the hardware will work on your older Yakima RocketBox. These are designed to fit the RocketBox 15S, 15, and 11 that were manufactured from 2005 to 2011. If you have a different model RocketBox you will likely need to modify the box itself for these to install.

  • Parts Needed to Mount Yakima Space Cadet Cargo Box on Roof of 2008 Honda Odyssey
    In order to mount your Yakima Space Cadet Cargo Box to the roof of your 2008 Honda Odyssey you will indeed need to add crossbars. For your Odyssey that features the factory raised side rails I recommend the Yakima CoreBar System. This roof rack consists of # Y00421 for the two 50 inch CoreBar Crossbars and # Y00147 for the TimberLIne Towers that will attach to the side rails. I have attached a short video demonstration on this roof rack that you can check out. As long as you still...

  • Replacement for Yakima SpaceCadet Cargo Box
    I checked with Yakima and the SpaceCadet cargo boxes do not have replacement lock housings available due to the age of the SpaceCadet boxes. The only parts Yakima has for these boxes are Replacement Mounting Hardware # 8870098 and Yakima Replacement Luggage Knobs for Pre-2002 Cargo Boxes # Y8870048. While I know it isn't the answer you wanted, the only option, if the housing is broken is a new cargo box. You can get a new one without a huge cost associated with it, such as the Thule...

  • How to Mount Yakima SpaceCase Cargo Box to Factory Crossbars on 2020 Subaru Forester
    I do have a solution for you, however I reached out to my contact at Yakima and he said the Universal MightyMounts # Y03590 aren't compatible with your older SpaceCase Cargo Box. The mounting hardware for the SpaceCase is a bit different and you won't be able to properly attach the MightyMount clamps. Your best route for mounting the SpaceCase to the wider aero-style factory crossbars on your new Forester is to replace its existing hardware with part # 8870098. This kit consists of...

  • Mounting Hardware Compatible with SportRack Rooftop Cargo Box
    The SportRack Replacement Hardware Kit for Explorer and SkyLine XL Roof Mounted Cargo Boxes # SR05587 has basic components for mounting. Just the crossbar mounting hardware for this kit is found in the Replacement Hardware Kit for Searsbox Cargo Box # TH05603. Not all of those components are available separately, so you will want this kit for all those parts. Not all mounting hardware will work with this box even retrofitted, so if you want further options for your crossbars, you...

  • How to Fit Yakima RocketBox 15S on Whispbar S53 Roof Rack System
    Although it isn't designed for your Yakima RocketBox 15S, you should be able to utilize the Replacement Mounting Hardware # 8870098 for your application. The U-Bolts are 4-1/4" wide so they will fit around the Whispbar S53 crossbars and then you can fit the ends of the U-Bolts through the slit in the bottom of your cargo box and secure them using the plates and knobs.
