Hey all, i'm looking to add some subframe connectors to finish off my 1970 Nova suspension/chassis. The car has Hotchkis springs front and back, refreshed balljoints and bushings all around, and a heavy swaybar. I'm looking to try and get the car to feel more modern/solid, the goal is more of a mountain road cruiser than drag racer. From reading around here it seems most people run the Summit/CE type that is a straight square tube or the Detroit Speed type that you have cut up the floor. I am not super impressed with the design of the CE/Summit type (if you run these please chime in and lemme know your experience) and while i'm not opposed to welding at least the back half in i don't really want to cut up the floors... So that's why i'm looking at these alternatives.

Has anyone run the Alston type? They look similar to the global west, but i am having trouble finding any information on them. I am also considering the regular Heidts type as i think they look like a better/simpler design for a bolt in than the CE... and i don't really want to spring the $$$ for the Hotchkis which looks the best in my opinion.

You guys think the Alston/Hedits is really worth the extra $70-100 over the Summit branded ones. The Hedits also looks simple enough i might be able to fab it myself if i could figure a decent way to reliably/consistently bend that square tube.

For reference:

I have the Heidt's on my '72. They bolted right in.
Quality good.
I'm happy with them.

Thanks for the tip, ill check em out. You got any photos of them on the car? only ones i can find are camaros. I'm more interested in if/how the tube is bent to clear the floor...

That's one of my complaints of the CE ones is i feel i'm gonna bash my shoulder on the tube that is hanging down.

I bought the weld in, cut the rear floor boards type of subframe connectors. I can’t cut them in until the car is assembled so I can’t tell you how the install goes or snap a picture yet.
The reasons I bought this type are firstly to get the most out of strengthening the car structure. I don’t see how a bolt-in will strengthen as well. Secondly, I like how the welded version tucks up under the car and is much less visible than the bolt-ins that hang below the floorboards.

Yah the Detroit Speed Weld ins do look much better from a strength perspective. Reduces the ability of the rear to apply torque on the structure/keeps the points inline.

I guess i don't trust my welding skill enough to try and cut up the floors (i did replace the pass front floor pan though.) I'd also like to avoid removing any material like the floor pan parts. I intend to bolt and weld the rear, and bolt the front... Maybe to be welded when i decided i wont bash my shoulder against it when working under the car.

The only pictures i can find of the Heidts installed on a camaro:

Still never seen them on a Nova.

I have never found any pictures of the Alstons.

It looks like he did it with just straight tube... But i bet it hangs down like the CE connecotors.

Installed my DSI frame connectors today. I say it’s not difficult but with my son on the tools, he made short work of it. They tuck up in the undercarriage like they belong there.
