I just finished upgrading my 87 GXL to a TII diff. I still need to drive the car with the NA motor before I get all the rest of the parts I need for the motor / tranny upgrade.

Can I just slot the NA Flange as shown in the pic and get away with this for a few months?

I do not have a donor TII drive shaft to get the right flange from. Has anybody actually run with something like this and if so were there any problems?

i have always ran my 7 with the na d-shaft and the t2 rear end with no problems, but i didnt open my holes all the way like that so you might run into some strength issues if you shock your drivetrain

some people do it u will prolly get away with it.

Drilled out that far I would question the strength but it could last a while.

lemme see..you Slot the holes.OK..then you put the Driveshaft on..it Rotates at Say 8,000 Rpm..and since you have no Idea if the Driveshaft was Installed STRAIGHT because the Holes are Slotted,It Wobbles..It would likely take out the Differential seal,and Bearing....SURE.It's Safe...for Awhile..But,why Do things that you Just have to Replace Later?..it's your Nickel.and your Life,But I would get right stuff,and Be Done with it.

It can't wobble because it is hub centric (ive used that word for this several times but I still dont know if its the correct way of saying it). Although it could still be off balance from grinding more off one corner but I do not see this as being as big an issue in this case. Now if it was noticeably more on one corner then i would worry.

yes, i agree with you but to correct your facts a little, it actually spins at a more violent 15,000 RPMs...

If you have the replacable u-joint drive shaft you could just change the back yoke to a t2 one.

It will be fine for the short term. The shaft is centered on the hub.

The NA shaft is also quite strong.

Yes, that is true. but, it is still NOT a recommendable thing to do.

It will last plenty long enough, you're Running the N.A its not like you're putting a N/A shaft to a T2.

i done it on my SE(T2 swapped big turbo and 245/40/17 on the rear)but i didnt open the holes that much and never have any rear end or balacing issues,just line up the driveshaft to the rear end flange(make sure is straight)use a vice or a seaclamp to hold it together and tight the bolts down(its gonna be straight cause is centered by the hub)Now cause you took that much material you should get it rebalance just to make sure that it wont vibrate
