can someone plz post pics and install instructions for the spacers they sold with the ds? were they diff mount spacers or flange spacers?

diff mount spacers. lower the rear crossmember, put a jack under the diff and remove the 4 large bolts.

 

[berjet]

so they are changing the pinon angle by moving the chassis to diff mount lower?? how thick is the spacer?

 

[GMH GTO]

Don't belive its changing the pinion angle, it will change the driveshaft angle. However i've run chromoly 3" driveshaft then installed the spacers used a 3.5" alloy driveshaft acted the same way (in terms of critical speed).

 

[berjet]

the pinion angle won't affect critial speed but vibration and u-joint life

Heck yea Pinion angle will affect critical speed, if pinion angle changes, it will affect driveshaft angle.

Outside of 3* difference will cause a vibration.
