Difference Between Dexter Axle Heavy Duty Suspension Kits # K71-449-00 and # K71-359-00

Question

Question:

I can’t figure out the difference between K71-449-00 and K71-359-00. It says one is for 35” axle spacing and the other is 33”, but I can’t identify what part is different. Any help would be appreciated! Thank you.
