will many parts from 83 5kt fit 86 5ktq?

[Livolsi, Stephane]

Found a quite nice 1983 5000S turbo (non-Q) with auto trans tucked away in a
garage.  Apparently it has been there for a while (3-4 years) and has been
started periodically.  Has 5 bolt rims in good shape (only 2 hubcaps
though), interior and body look quite nice and to be honest the 4
rectangular headlights looks kinda sharp.

I think I can probably get it quite cheap, but realistically would only use
it as a parts car.

Would this car have the exact same MC engine, turbo, hydraulics, etc as my
86 5ktq?  Haven't had a chance to look under the hood yet.

Any BTDT, advice, info would be greatly appreciated.

Thanks

Stephane
