After much debate on what length I wanted my International S truck to end up, I bit the bullet and started drilling holes in the frame. Figured I'd go with what I have on hand and just shorten it the length of one driveshaft. Crap, says I can't post attachments.
Drilled about 20 holes in the frame, for 1/2" bolts. Took off one of the rear spring hangers to use as a template.
Measured the longest rigid driveshaft, 57 1/4"
Spring hangers were 58 3/4" bolt centers from forward bolts to rearmost.
Fudge the rear one forward 1", let the slip yoke take the rest and that lets me use the foremost holes as the rearmost.
Off with the tail pipe, driveshaft, various cross members, driveshaft safety hoop, undo all the spring hangers.
Two of the cross members were riveted.
Cut a square pattern on the rivet head, clear off the outer parts, leaving a square part sticking out from the frame. Wack it with a sledge, out goes the rivet.
Pitch leaf springs forward to clear holes, drill last six holes.
Air up tank so that brakes will disengage.
Find that axle is so rediculously heavy I can only move it with a come-along.
Jack up rear of frame, chain and come-along around axle, ease it forward.
Screwdrivers and a tapered punch/alingnment thing, along with a small floor jack to get the spring hangers lined with the holes.
Cross members had to move forward with axle, so crank on the come-along, then beat/kick/pull cross member to make it follow.
Air lines are same length, just have a loop in them. Exhaust tailpipe will be shortened and rehung.
Shock mounts are in their new spot, everything is bolted down.
Still have to cut the frame off, then fab up the hitch.
All original hardware used, so far I'm only out a few cutting wheels for my 4" grinder.
This was actually one of the easier parts of the build, went better than expected.
