Was installing heat exchanger tonight and discovered the @#$%ing mounting brackets had been soldered with incorrect spacing! Aargghh!
I should have tested it out before prepping and painting (3 coats!) the damn thing.
Anyway, word of caution for other novices out there: take lots of measurements before having a radiator shop take this thing apart.
I ended up removing the motor mount studs entering the engine block and positioning the heat exchanger such that the rigid lines fit just about right. (with suitable filler wood pieces to emulate the mount arm thickness). It appears that only one of the brackets will need to be removed and repositioned correctly.
Back to the rad shop tomorrow to have them fix it. Looks like all the fates are conspiring to keep me from driving to PUB ...
