Sherman,
I was trying to make a distinction between the S10 and other applications. All of the 4cyl and 2.8V6 S10's had a longer input shaft @ 7 1/4", but I'm not sure about the 4.3V6 versions. If someone could verify the input shaft length on a 4.3V6 T5, I would appreciate it. Same for the Astro van applications.
On that '87, make sure it uses a mechanical sender for the speedo.
John,
Right, the 49-54 cars are the only problem.
