Hey Joe, thanks for reaching out. We may have a 8 bolt hub option for you. In order to be sure you get the right parts I will need to know the axle weight capacity, inner and outer bearing sizes, and seal size. If you can remove one of the hubs and pull the bearings there should be a number stamped on each bearing, or you can measure the ID with a micrometer. Drop that info in the comments below when you have it. Hopefully we have a compatible 8 lug hub, otherwise the next thing we would look at would be replacing the axle.

Hey Joe, were you able to get those bearing and seal measurements from your Chaparral’s axle? Once you had that info, did you find an 8-bolt hub that matched up? Your results could really help others planning a similar swap.
