3 T5s Available In '89
So I'm looking at buying a driveshaft from Summit for my Firebird

Under "Transmission Type, it lists: MB1, M39, and MK6. Can't figure out which one I have.
Can anyone educate me?
Thanks

Check your RPO codes if you have them.
All the T5's were physically the same, I think the RPO code just indicates which overdrive gear was inside the transmission.
MB1 was for the 6 cylinder cars.
