Fitting an earlier 73 front to the later 81 up truck
« on: April 12, 2016, 08:34:42 pm »
Hi new to the forum, looking into buying a short bed pickup. Only ones I seem to find rust free are the 81 and up but I much prefer the older 73 front. I know there is a lot of thread posted with people fitting the later front to the older pickup and it looks way too involved for my liking. My question is has anyone done the opposite and put the 73 front clip on the 81+? Is it any easier as far as fab work? Or does it still involve cutting etc?

I'm gonna be looking to do this with my 87 k5. Basically I'll need everything from the fire wall forward. Correct?

Everything from the fire wall forward. Including the windshield wiper stubs.

Physically yes but depending on your set up the threaded holes to mount the radiator/shroud may not be there.  I've also heard the core support frame mounts need to be moved some.

As far as radiator goes there are several different top mount set ups. You might have to mix, and match some parts.

70's is 70's, 80's is 80's you cannot mix and match between them without custom fab work, however the three different grilles in the 80's (single head light, dual stacked lights, and dual side by side lights) can be interchanged if you change to the appropriate rad cradle/core support without swapping fenders or hood

You DO NOT need to move the core support mounts on the frame.
As said already you will need EVERYTHING from the doors forward, including the windshield wiper stubs. If your truck is the two head light system the wire harness will work with the older round head light nose.
