when going to a ford 9 inch do u have to change the driveshaft too

 

I am not for sure but *i think* you can get by having the Ford Yoke welded to your rx driveshaft or maybe even bolting the 4 bolt flange yoke to the rear end.

 

need a custom made for that modification

 

yep you need custom shaft made. http://www.grannysspeedshop.com/ sells them.

 

i went to that site and nothing

 

give them a call they make them directly. i have a ford 8" and i got mine custom made by them. but they are a bit pricey but it was custom build from the ground up and well balanced.

 

i actually put the wrong site this is the correct one http://www.grannysspeedshop.com/

 

I cant believe this ****. you're at it again.

 

what do u mean at it again

 

driveshaft specialist in asuza can do it for less than $300.

 

I have a driveshaft already done.
The front will fit any NA rx7 transmission and the rear is a ford flange.
Fully balanced .. Large diameter tubing from a B2200 truck,

I have gone to a toyota rear so no longer need it.
