I’m about to install a Keisler RS 500 five speed in the El Camino; should arrive next week. This transmission is three inches longer then my current M22 so it comes with a new drive shaft.
As a result, I’ve been trying to educate myself on driveshaft alignment. While doing some research I found this site. Lots of good information, I’m sure there are those here that could teach a class on the subject, but I’ve learned a lot from this site.
