I have a 67 GTO (non post) and a 67 Tempest post car. The tempest was purchased as a donor car for full rear quarter panels. The tempest is much better condition than the GTO.

What would be involved in using my GTO as the donor and converting the tempest to a non post GTO? Just looking at the options!

It would involve more than you can probably do.
Since you have both cars, open the doors and take a look at the base of the windshield posts. Starting there and going up and back, run your hand along the edge until you hit the rocker panel.
That's the part you have to replace, from there to the back bumper.
I'm serious.

Cut thru all 4 windshield posts@ exactly the same place, cut both cars thru the rockers and across the floors at exactly the same place and weld the car back together that you want to keep. It's called replacing the rear clip..........nothing to it !!!LOL.

It can be done, but it not for the faint of heart

Not that easy. The A-pillars are different. Look where the coupe door seal contacts the pillar vs. the hardtop pillar.
I'm not taking wild guesses on this topic. When I stripped down my post coupe for parts it sat next to my hardtop, also stripped. I compared both gutted cars just to see what it would take to convert a coupe.
Other items that differ, a-pillar stainless, side glass, 1/4 window regulators and the structure it mounts to, belt line trim, inner stainless side trim, and the obvious such as the 1/4 window opening and jamb at b-pillar (post).

Besides, clipping won't help. The post coupe is the one with good 1/4s that he wants for the GTO. If he needed a cowl for the Goat, then he could swipe it from the coupe.
I can and have cut a car in half and put it back together. This is not one I would do.

Thanks for the comments.

I could have missed the A-pillar difference where the door seal contacts the pillar. It definetly tapers off at the top on the coupe. Fortunately, the A-pillars are good on the coupe so we can remove the spot welds holding the top to the A-pillars and go from there. There is also some issues with the bracing in the coupe top. I will let you know how it works out as we attempt to replace the rear clip.

The GTO body not only has a lot of rust in the rain gutters, it has been hit hard on the passenger side rear corner. It has also been hit just behind the drivers door. The post body is good shape.

The GTO is a factory A/C car with an automatic, power steering and power brakes. It will make a great driver.

well, the VIN wil give it away whenever it is sold and then the price issue will come into play. This will be very difficult to do without a jig.
