He only needs year, model and your option preferances. weight capacity, brake size, torsion arm down angle in degrees, high or standard mounting bracket and shock brackets. Pay him he submits order pay shiping to your choice. I've bought from him 3 times best price and perfect fit. Heed Actions warning, after
1962 torsion axles were bolted on. But in
1962 some early models were welded, meaning you have to cut them off without damaging the side plate then drill 5/8 holes to attach new. The shock mounts, some say shocks are not needed. My responce, there a no charge option and take a ride in one towed without shocks! 10 inch vs 12 inch brakes? Yea, you do'nt need 12 inch. Untill you do! 22.5 to 45 degree down angle on torsion arms? likley 22.5 original. I opted for 45 degree for more ground clearance on my old 22 ft. Same for the "High mounting brackett". 1 inch more clearance on the bracket. Gave me 3 or 4 inches extra clearance, usefull for boondocking. Saw no issue in towing. Last envoice 16 months ago, complete axle delivered to home $700.
