I've been running a 84 vett front susp. and a 9" rear for 15 years (good combo)
I have a 86 vette dana 44 ( 44 are from the stick trans) sitting in the garage (ebay $750 and $170 for shipping) I hope to go around corners faster
the drag strip will not allow IRS if you go faster than 11 sec or maybe 12 im not sure what time it is for the 1/4 mile, iam not in to the drags, I want to try auto cross
the vette front was very easy to install
the rear looks like it will be easy also (just not sure what angle to set the 4 links from the rearend to the frame
