OK, I searched for nearly an hour and couldn't find a decent answer to this question.

I have an '89 GTU with the 17:1 RPM-sensing P/S. Is the 15:1 P/S rack from an '86-'88 a bolt-in replacement? In looking at pics of the two racks they look like they have the same line connecting points, but it's hard to tell.

I know that the later speed-sensing rack is different and won't swap directly in, but I can't find anything about the earlier 15:1 rack.

Thanks in advance...

It will bolt in place, but to get the power steering working properly, you'll need the 15:1's pump, lines, and computer. And maybe the harness/connector (not sure).

The 15:1 rack IS the velocity sensing rack.

 

Thanks for the info. I didn't realize that the '86-'88 had the velocity sensing rack - I thought that wasn't put in until the '89+ models.

No, they cheaped out and started using the RPM-sensing racks in 89.
