I guess so, curved guys that fit over the loose caps, with a circlip to keep the cap on. they hold that end of the shaft to the yoke on the front differential. I just about couldn't do it, one or the other of the circlips kept popping off, finally I did the one small crank with the ratchet at a time deal, going around and around evenly. Extremely tedious as not enough clearance to get much of a swing on the ratchet. Oh well, got it done, wayyyy slower than a real mechanic would do it I'm sure. Now if the straps themselves had a raised boss on them, then two points of "keep" would have kept the clips in while they were being compressed.
Of course maybe I was supposed to just bolt it up, then try to needle nose pliers the clips in, but..I did it the other way that seemed easier and more do-able, as the clips are stout.
This has been a real long term get a real cheap roller hunka junk running and working, with a limited budget and even more limited knowledge base.... hehehehe. I just keep putzing away at it, fix what I can when I can, go on to the next whatever. It's functional now, point A to B,(quite good actually), I've used it some going to town, hauled a load of scrap, done a bit of firewooding with it.
