Would my stock radiator work on 73 engine or would i have to use a radiator the same year as the engine

Should work. The mounting holes locations from one radiator to the other may be different. So you may have to drill some new holes. If the newer radiator comes with a shroud,use that too!

Is the outlet and inlet on both radiators the same location?

Using the old water pump would have the lower hose connection on the correct side. You can use the old radiator. 1969 and earlier water pump.

Thanks guys im still learning. Im glad i found this place thanks.

Would my transmission cooler line work good on the radiator to or should i just buy a separate trans cooler radiator. My water pump exits on the opposite side that the radiator does. Im just trying to work with what i have. Thanks for the advise guys

The lines should work as long as the coupling nut on the tranny cooler lines are compatible (i.e. same size) , If you have a flare nut wrench make sure you use it so you don't round out the fitting. Did you have that newer (old ) radiator checked out before you put it in? As long as you have it out, I would take it by a radiator shop for a pressure test and clean out.

Just cheap insurance...to do it now.
