I want to install the TF rear upper rear control arms and adjust the pinion angle to put stock rezeppa ds at 2 degress.
then later on will install the Coast shafts. My question is can i run the rezeppa stock shaft this way untill i install coast shaft.

 

Yes. You can install them & correct your current pinion angle before getting a DC shaft.

 

I've installed a full set of Metal Cloak control arms & I'm running stock shafts with no problem.

 

Don't forget that the rear uppers come in 2 different lengths. If you are going to use them in conjuction with just the front LCAs; get the extra short uppers. Eight arm setup; regular length upper
