Replace the rag joint with a u-joint....they will bend right behing the steering gear & rip that rag right right out. I don't know when or if they switched to rack & pinion. U-joint off an Astro van column has the right splines to mate to the Gremlin box.
Chain the humps. There is a fairly stiff plate under the floor right above the rear axles that works well for it.
If you can do it....weld the lower core support to the frame, or it will rip out.

ive never built one but a guy has brought the same one two years in a row to our fair and cleaned house....he runs a 4.3 with a 350 trans slip shaft and 9" ford rear end.....a sub frame fwd 4 cyl has little to no chance of beating it....

C4 is right. Definitely replace rag joint. If you're allowed on your 78, I'd see if you're allowed to swap the front bumper shocks out with something bigger. If you notice they are the size of a broom stick in diameter compared to a beer can on the 74-76. Even seen guys take the back straps and shocks off 74-76 GM sedans work real good.

I have a 74 w a 1 st n 2 nd place on it. The back rolled up and I lost the bumper the first go but welded it back on and the front is bent up now. I will try to put some pics on here. The a arms are the weakest I think.

I don't use anything but the nose with these things. but I don't drive like a retard either. just aim for tires and your car won't break. With the front suspension welded up you'll be bending/breaking tie rods, A arms, rear ends when you hit people.
