I have an good '84 with a dead 700r. I have a dead '88 with a good wc trans. Any advise on putting the wc in the '84?

You will need the pedals etc. Are they both V6 or both V8? If so fairly straight forward but I can not say about the speedo. For the wiring look to the bottom of the T56 swap page 3 for some of the info. He covers the auto to manual wiring plus part of your back up light wiring. Worth the reading especially with the pics.

Re: 700r to wc swap

Thank you for your response. I have started disassembly of the donor car and it looks pretty straight forward. Will I have to cut openings for the clutch and shifter holes or are there knockouts? Any tips for unbolting the bellhousing? Thanks again.

Re: 700r to wc swap

Make sure to have the torque arm bracket bolted up on the trans already i had this problem yesterday also make your cut in the floor from under the car so u dont run into setting the interior on fire due to the sparks from a cut off wheel also when installing the pedals remove the steering column makes it alot easier to see while under there

Re: 700r to wc swap

Thanks Soarestransam but I didn't understand about the torque arm being bolted up. I read about your trouble with alining the pilot bearing and the flywheel, did you resolve that issue?

Re: 700r to wc swap

The holes for the clutch master may be recessed or marked but they are not knockouts and not all cars had them marked. Do not trust the holes in the padding to be in the proper location. Put the pedals in, mark locations of everything, pull then out and drill and cut your holes. The shifter hole seems to be the recessed area under my console but I would only cut what I needed plus a little.
I haven't done it yet but it is my understanding that the torque arm bracket needs to be put on first because the top bolt is very hard to get to when everything is in place.
