Well I am not deciding on one or the other, going to for sure keep the 81.

For sure will not be driving the 79 because it is really banged up, and live in a townhome where I have 2 spaces. Currently have one for my wife's car, one for the 81, and am parking the 79 down the street a little ways away.

The reason I would keep the 79 is for major components like the tranny and engine, because the engine\tranny in the 81 is not running close to as well as the 79.

I guess im asking will the parts transfer to the 81? I cant really sell the 79 to make the 81 run like a top, because in order for me to do that I would need new engine and tranny 81 = blowby and the 79 = no dancing cap, and no vapors commin out.
