Dear Welder Series…
With your WS14340 Mustang II kit, what rack and pinion options can I use as far as a donor car? Thanks.

Dear Bart…
The passenger side rack mount is slotted so you can use a stock ’74-78 Mustang II manual or power rack or a later T-bird power rack. If you use the later rack, get the rack spacer kit #24410.

Thanks for looking at Welder Series’ parts.

Paul Horton

Dear Welder Series…
Do you have the years of the T-bird rack? I have a 1990 cougar xr7 parts car.  Thanks.

Dear Bart…
The ’79-93 T-Bird rack is the one to get. Better check with a parts store to confirm that the Cougar used the same one.

Paul

Dear Welder Series…
90 Thunderbird and 90 cougar are the same but there are different part numbers for different years 79 and up. Just want to make sure before I order this. Thanks for all of your help.

Dear Bart…
When we were building cars, we would think we had dialed in the right application, but when we ordered the same number from the local jobber, a different rack would show up. The differences seemed to be in the casting at the input shaft. Some casting were larger and would touch the crossmember. It might not have mattered in the stock application, but it did to us. I don’t know how to help you get the right one.
Sorry – it should be easy, shouldn’t it?

Paul.

Dear Welder Series…
This will be my first attempt at a rack and pinion swap. I’ve done everything else from falcon v-8 swaps to auto to manual swaps and the sorts. Just like to have a good idea of what I need. I can’t see that the travel of the rack over those years would have changed that drastic and if some “clearancing” is needed it should be that bad….I hope. If not, I will go buy a new mustang II power unit. Thanks Paul.

Dear Bart…
Bart, I agree with you that the rack travel is probably (about) the same for the T-Birds and Cougars. I’d likely try the rack you have. If it fits, you’re a winner.

Paul
