I don’t have a master parts catalog for a 37’ master. I’m putting a modified (51’ 3.55 gears) in 37’ rear into a 34’ pickup. The guy I got the rear from sent me two spring perches but both perches have the same two numbers on the top and bottom halves. They both appear to be right side perches because of the angle of the spring pad area. The top half perch is 472506 and the bottom or saddle half is 472508. Can someone tell me the part numbers of the other perch. Thanks

While mine is a 38 truck I think the cast pieces between the rear axle housing and the springs are interchangeable side to side, or at least mine is.

5.403 33-37 CC DC EC FC GA GB w/cap (cast 472506) part # 473601 2 per car

No mention of 472508, probably included in 473601? This would be for Standards (only) through 1936, and the new hypoid "car" rearend in 1937 if I am reading it right. Apparently no difference right to left.

5.403 34 DA, DB, 36-46 1/2Ton w/cap (cast 373345) L part # 600175 1 per car
5.403 34 DA, DB, 36-46 1/2Ton w/cap (cast 373346) R part # 600176 1 per car

Apparently different on a truck? Axle tube size bigger?

Great. Thanks so much for the info. The gentleman who sent me the perches has three or four more so he’s going to look at what he has to see if there’s different numbers on them but go in by the pages you supplied me, they’re the same on each side. I really appreciate the quick reply.
