View Full Version : FJ40 Rear Driveshaft - V8 Conversion

10-12-2008, 04:43 PM
New to this Site! So, I have a 71' Fj40...my wife purchased it for me two years ago for my birthday. Lightly massaged 350, SM420, with stock transfer(vacuum)case. The rear drive shaft CV joint, coming from the transfer case, has completely gone. It's still Toyota bolt pattern, so it will fit standard U-joint. My question is this - I'm evidently going to have to have a driveshaft custom cut and welded, since the length is no longer stock. So, would this be a good opportunity to reverse my rear leaf springs, gaining the extra three inches of wheel base. I would also like help in finding a place that would give me the best price/quality? Any advice would be greatly appreciated!

It would be a great time but don't skimp on doing it right and build a anti wrap bar too!

Okay, Uncle Ben, you are suggesting that I go ahead and reverse the rear leaf springs? Also, put in an anti-warp bar?

Where would you recommend I go to get a drive shaft?

Thanks again!

There are 2 or 3 great driveline shops in the metro area. We southside guys use Englewood Driveshaft, 3364 S. Broadway, Englewood, CO 80110. (303) 781-0554

When you say reverse springs, you're just flipping them around so the military wrap is on the other side? you're not talking spring over...

Nakman - I already have a spring over, so yes, that's what I mean, just flipping them. I'm running 37s, so I could use the better positioning of the rear axles.

Thanks for all the help guys!

Just checking to see what everyone thinks of Rocky Mountain Cruisers - owner's name is Ron?

Good question. I've been trying to get a hold of them this morning with no luck. I'm new to the cruiser scene, though, so this is my only experience with them.

Ok so if you're sprung over then I'll definitely second the anti-wrap bar suggestion. And my experience with RMC is they're very good, stand-up folks who seem to be perpetually booked up. For a driveshaft, I'd go elsewhere for sure.
