Torsion Bar Boots???

[1969383S]

I'm not too damn sure those seals are all that important. After all the LCA's don't have 'em, and the BACKS of the bars are exposed...............

They are only because the dirt and crap flows that way. The fronts are better protected.

I see no reason for poly pieces as you just want to keep the dirt out. The factory type are still available from the any dealer and many others. Put them in hot water for a bit and fashion a sleeve from a cheap funnel and they go right on. Load with grease and slide the boot over the receiver. No need for fancy stuff here.
