This is a re-post from the general third gen forum. I wasn't getting much response, but thought some of you checking here might have some info.

I am in the process of swapping the third gen RX-7 suspension to my 73 240z. Notice I said in the process. By that I mean the entire suspension is pulled off my Z, and ready for the transplant. Originally I was going with the late model 300zx,(90+). However, the track width is rather wide compared to my Z, and the RX-7 is nearly the same size. Besides, all aluminum, lightweight, and a know quanity on handling.

I am trying to find out the mounting setup for the upper a-arm in the front, and the lower link in the rear. In other words, the parts that have to be fabricated and are not attached to the subframe/cradle. Any links or pictures are greatly appreciated. Ones with the wheels removed are the best, as well as shots from underneath or down in the engine bay w/o an engine. I have already found this site:

Also, I know the rear diff/cradle is attached to the powerplant frame,(don't know the real name, the brace from the tranny to the diff). Will I have to fabricate a mount/support where that came into the rear suspension?

I have yet to find a suitable donor car,(still a few salvage yards left that "say" they have what I am looking for).

I appreciate any help you can provide. BTW, the engine to motivate this is the r-33 skyline gt-r RB26dett.

Basically I sold my BMW M coupe to finance this project. I wanted a great track car that was a sleeper. The RX-7 suspension coupled with the RB motor in the lightweight 240Z chassis should be a great combo, providing I can make it all work....

Thanks in advance for any links or pictures. Also, if you know anyone in the Noforlk, VA or 3-4 hour away area that has suspensions for sale, I would appreciate the information.

Bob there is a 240Z track car over here with a std RB25 which is hell impressive! I might have some answers for you as I am doing the same suspension thing to my 20B 82 Cosmo. FD front upper A-arm fixes into the body at the foot of the spring tower. There is some heavy bracing of the sheetmetal, but nothing impossible I'm sure! I have a front crossmember from a 20B JC Cosmo just in case it is too hard, they have what is basically the FD front end but the crossmember/subframe carries all the suspension parts

Not sure what you mean by the lower link at the rear, I bought a complete rear assy. & all the arms & adjustment rods locate into the subframe. The differential is only supported at the rear and the the link to the gearbox supports the front so yes you will need to fab up a front mount for the diff, or tie it to the box. I havn't got so far as deciding which way to go with that myself, I have access to the FD brace but fitting it in the tunnel would be major!
