Doing a D36 upgrade?

I've got some rough measurements, I need to get more precise measurements 3mm is enough to mess up an alignment.

yes im putting a d 44 in place of my 36 and just wanted to make sure everything will fit. are the half shafts the same as the 36 also?

BrianCunningham

the batwing's the same width, the driveshaft is different, not sure on the halfshafts,

WVZR-1

Did you buy the rear on Craig's list?

Everything is bolt in! The "bat-wing" mounting is identical to your D36 now. The drive-shaft is something near 1" shorter on center of the u-joint yokes. You'll need to swap the yoke from your D36 shaft to the D44 shaft if you buy one and have it balanced. A wiser move might be to have your D36 shortened, replace the joints and have it balanced. You either need a D44 C-beam or you need to drill your D36 beam to fit. It can be done. Half shafts are the same. The search function works well enough on this forum so that you should be able to help yourself.

no it didnt come off craigslist im getting it from a forum member. it came out of a 1990 zr1, im getting the rear with batwing, driveshaft, and the c beam. i wasnt really sure about halfshafts, but im just making double sure everything will fit before i get it. thanks

If everything is from the same car you're good to go! You'll need to swap the slip-yoke on the drive-shaft to match your trans. You might as well accomplish the transmission speedo gears while your doing the build. What tire are you running and what trans? What gear is supposed to be in the ZR-1 rear? 3.45 would be stock! Where is the rear coming from?

i have a 3.54 gear in the 36 now and the 44 has a 3.45 so the speedo gears should be pretty close if not then i have an adaptor box that i can move the dip switches to get the proper ratio. im keeping the stock tire and the trans was built with the best money can buy but still used the stock trans gear ratios. rear is coming from a forum member. thanks for your info, that makes me breath a little easier knowing all i have to do is bolt it in.
