i'm looking to swap a full SE rear end into my GS. i know the proportioning valves are different but what i'm curious about is the hard brake lines. will my GS hardlines reach all the way to where i hook my SE soft lines up to (btw i'm replacing these with steel braided)? much appreciated.

81-85 the same if you plan on replacing the soft lines make sure to order the right year and if disc or drum.

 

wicked. my cars an 81. so the hardlines will hook up to the softlines in the SE diff. i just have to get the SE proportioning valve?

 

they should the are the same thread pitch , not sure if you need the proportioning valve it was recomended to me to put it on my 79 sa when I did the swap.

 

great news. thanks man. i'm off to go get me an SE diff.

 

oh geez. just had another thought. driveshaft? will it bolt up?

 

-SE Diff has the large flange, 81' will have the small flange.
Large flange is 83 1/2 -85 cars, not sure if that was with or without LSD models.

So no, your 81' drive shaft will not bolt to a -se diff.

 

alright...i think i've got an SE driveshaft hidden in my garage somewhere. will that slide into the tranny?

 

Yes it will

 

we're in business.
