Hi, will anybody know whether;
a) a 88 NA lower intake manifold will interchange with a 85 turbo manifold?
b) will the 85 top feed injectors fit onto the securing tabs of the 88 lower intake manifold as the 88 NA and the 85 turbo have different injectors?
c) will the 88 NA upper plenum fit onto the 85 turbo lower intake manifold?
will the 85 turbo upper plenum accessories swop over to the 88 NA upper plenum?

Any answers will be very much appreciated.

a) yes.
b) I understand there's an issue with that.
c) yes.

I had to grind an angle into one corner of the insulators to get them to fit flush.

Careful......they smell like asbestos so they probably are.
