Pinion Flange ?'s

I'll be starting my T-56 swap soon, so I'm getting the final details sorted out, and I have a few questions...

I was wondering about the pinion flange install. Is this pretty much the gist of it: http://www.mustangforums.com/forum/2...ll-w-pics.html

When installing it do I have to worry about crush sleeves in the rear end coming loose, or changing the pinion depth? I just paid a lot of money to have my rear end built strong, and I'd rather not break it! Anyone have any experience with these things?
 
Why are you even messing with the pinion flange?? No need to on a trans swap. Is there a particular drive shaft you are trying to use??

Because no factory driveshaft will fit on the 97 Cobra with the T-56. My other option is to shorten the driveshaft I have for it, but the pinion flange is $20...so I'd rather go that route, since an already shortened driveshaft is $500 and having one cut/welded for me will probably be $100 or so.

Do you have a 1350 flange on there now?? Are you sure a 03-04 Cobra driveshaft will not fit??

Everyone I've talked to who has done the swap says I need a shorter driveshaft, new pinion flange, or a different weaker u-joint

Well the 03-04 Cobra driveshaft is shorter than your stock one. I assume you know they have T-56's from the factory.

You said your 8.8 is built already so does it have a 1350 flange?? If it does then a stock Terminator driveshaft will bolt right up.

or if not, get a shaft made, a new shaft can be made for under $250 usually
 
Alright, here's the info I'm going off of here...

"It depends on which T56 you use. If you use the one from an 03/04 Cobra and you want to use the driveshaft for the T45 then it will need to be shortened and also have a 27 spline yoke installed. If you use the Yoke that came from the 03/04 cobra you will also need a Precision 448 U-joint to adapt it to the t45 driveshaft (the 96-98 cobra uses 1330 U-joints, the Terminator uses 1350, the Precision 448 joint is a hybrid joint to adapt 1350 to 1330). If you use the Terminator driveshaft with the Terminator T56, then you will either need to swap the companion flange (flange on the rear end of the driveshaft) from the T45 driveshaft (this will also require a precision 448 U-joint) or you can swap the pinion flange on your rear end to the one from a Terminator. If you decide to swap pinion flanges, just install the terminator driveshaft and call it a day. If you decide to swap companion flanges, then you may or may not require a driveshaft spacer to get the correct yoke protrusion on the transmission."

When the rear end was built it received 31-spline axles, new FRPP LSD, new ring and pinion, and all the bearings/shims inbetween, nothing else.
 
Yup, so the quickest/simplest way would be to get a Terminator driveshaft and use the Precision U joint. But the strongest option would be to still get the Terminator driveshaft AND pinion flange (both 1350) for the 8.8.

I already sold my driveshaft or I would have been happy to help you out. Check out some other forums, stock Terminator driveshafts are all over the place for sale, or you can get a new one from FRPP.

I already have an FRPP aluminum driveshaft for an '03 cobra, I just needed to find out how to make everything fit!

So, I need a 1330 U-joint and a companion flange, or am I totally lost? Can I pull either of them off my T-45 driveshaft?

What I think Jake is trying to ask is this:

he has a 97 cobra... he has a T-56 to put into it and the question is one of size, can he use his driveshaft that is on the car now by going with a different flange like he was told elsewhere, or will he need a shorter shaft no matter what?

If you already have the shorter driveshaft then just swap the U joint on the end of it and leave your pinion flange alone.

Ok, I think I got it.

Put the T-56 into my '97 Cobra. Use the T-56 shaft, and put the T-45 companion flange on it, and order a 448 U-joint to put onto the T-45 flange. And that's the end of it, am I straight now?

If you say you bought an 03-04 Cobra driveshaft it will already have the correct slip yoke for the T-56, so you do not want to put the yoke on from the driveshaft you were using with the T-45.

And yes you will need to get rid of the 1350 u joint and put on the 448 to mate up to the pinion flange you already have on your 8.8.
