Tony,(see the bolt and spring on the rhs of jeep picture) I am not familiar with your truck, but in saying that, the mount is fairly simple. The anchor I would call it, probably has a hole in the side (centre) This takes a spring in the hole. the spring goes in, and then the band slides on the square over the spring (which you have to compress to get the band assy. on)
A bolt with a tie wire drilled head screws in through the band into the anchor casting. when the other end is all sorted, this bolt is adjusted so that the lining is just clear of the... I'll call it the drum. When the hand brake is applied, the band is pulled in onto the drum against the spring. When it is released the spring moves the band back against the bolt head, giving the lining and drum a working clearance (the amount the bolt head allows the spring to push it away) The bolt is located by the tie wire.
The aim When you have the other end sorted out, is to have minimum travel of the h.b. lever while also having the lining clear,and the drum turning freely (which is important from a fuel consumption/ power/happy truck/ happy driver point of view.
Find a Dodge military manual (1/2 or 3/4 ton) or parts book, for a decent picture.
Hope that helps?
