Re: Driveshaft question
I’ve installed a shaft from an 82 mini truck. Fully compressed it is nearly identical length of a stock zuk shaft. Fully extended it is right at 2.0-feet long, which is about 2.0” inches longer than the zuk shaft fully extended.
If you have the large flange Samurai (post 1988) you can drill the flanges. Be warned that alignment is critical. I drilled my pinion flange on the bench and it worked perfectly. I could not measure a difference between the holes based off of three reference points – all measured exactly the same with a rule.
I drilled the t-case flange under the truck – big mistake, should have spent the five minutes it takes to take the flange off and do it on a bench. My holes ended up being about 1/16” off and it vibrated like crazy. So I ordered the Rockrat adapter for that end. The adapter was quick and painless. If you have the large flange, you have to drill for the small flange bolt pattern to use the adapter. If you have small flange stuff (pre 1988), it’s a direct bolt in. I used a small flange d-shaft I had laying around for a jig. I clamped the small flange d-shaft yoke to the large flange on the t-case end. Found the right sized bit, just stuck a hand drill into the d-shaft yoke holes and drilled it. The adapter works perfectly.
If you have large flange and feel confident that you can drill a circular pattern into the flange with tight tolerances, you don't need the adapter.
If you have small flanges, it looks like you will be giving Rockrat a call.
