78 Radiator in a 83?

[MTBLAZER89]

Is this a possible swap with some mount fabbing? If so what are the differences in the mounting brackets and such.

i have cobbled what you are trying to do, only the opposite. the only difference is the height of the radiators. IIRC you will be getting a smaller radiator. i beleive the 80 and up are slightly taller. as long as you have the correct radiator bracket that mounts to the radiator support you should have no problems. you may have to take out the grille and run bolts with nuts on them through the radiator support. the stock setup has nuts tacked in place in the correct locations.

i put my 83 radiator in my dads old 78 blazer with no modifaction. my radiator is the 19" core not the 17".

OK cool it's not a stock radiator thats in it. The one from the 78 we want to swap in is bigger and a 4 core /forums/images/graemlins/thumb.gif
