my truck is a 1991 chevrolet 1500 4x4 automatic. the rad is from a 1989 chevrolet 1500 automatic. would it fit?
both trucks are 4x4
both rads are 34 inch wide
both trucks had a 350 in them
 
if it looks the same and if you measure mounts on bottom and if the hoses same places and if the transmission lines same place most likely yes but easy to measure anyways
 
physically it will fit but do they both have the same engine? The 305 radiator has less cooling cap than the 350 radiator so if the donor truck has a 305 in it, it won't cool as well.
 
You can compare specs and model numbers at RockAuto.com

According to RockAuto, they use the same SERIES of radiators.
There are four different radiators used -- a combination of whether or not it has an auxillary oil cooler, and whether or not it goes between tanks (Not sure what that means). But all radiators seem to be compatible at least between the two years. The "Between Tanks" is wider than the normal one.

As long as they have the same dimensions and have / don't have the engine oil cooler, they'll swap.
 
it should fit right in as long as the hoses will hook up and has the ports for the transmission lines.
