Is it possible to install a 350z differential in my 73 240Z? I'm doing the motor and Trans and would like to keep it all together with rearend. Thanks IN advance for any input.

Welcome to Nico!
Yup, it's possible, cut weld repeat. AZC and TTT both sell aluminum mustache bars that accept the later shortnose r200's. I would be surprised if Gabe at TTT wasn't willing to mill one up to accept the single mount found on the back of the z33 diff. Of course you'll still need to work out the pinion mount but the short nose mounts they sell are likely pretty close and could be adapted with little effort. But you're probably better off sticking with the earlier diff's, from the Q45 or similar, same gear ratio, bolt in kit already available, also comes with the almost open VLSD found in the majority of Z33's. The even earlier Longnose R200's are an even easier swap but the VLSD version is hard to find and requires a bit more work to get in, and the CLSD version is very hard to find.
