Good mention Garry, I've seen those crossembers and like their design aethstetic. They are a nice piece with the only points against them that I can see is the price you mention (not too bad actually for a quality piece) and the fact that their geometry extends straight out off of the frame mounting surface and therefore doesn't provide the absolute highest possible ground clearance. If you want to acheive the kind of exhaust ground clearance you see in this photo, you're going to need a crossmember that arches up into the floor pockets of a 1st-gen like the new Hooker crossmember does.

Thanks for bringing that double hump idea for exhaust ground clearance , my eyes aren't what it used to be & I was planning on buying it for my Nova build so I would've been not to happy. If they did one up like Hooker dual hump , this would be the ultimate crossmember for all tranny. Thanks again , Garry

Since most crossmembers are designed by non-exhaust companies, their design geometry is rarely approached as a quest to maximize exhaust ground clearance as a primary design feature and it seems as though it's only been a secondary concern in most designs.

Bump from the dead, why not make your own?
It's what I am going to do now.
It's only metal, does anyone really care how nice a crossmember looks like under a car?
Budget guys don't care and ill be one of em.

Just food for thought. I'm currently in the process of installing Holley's 4l80e transmission crossmember in a 1967 camaro and the humps in the floor for clearance were not tall enough for clearance so I had to end up cutting the floor humps out and am currently in the process of fabbing custom covers. Just sharing my experience since they may not be bolt in friendly in every car.

I have an LSA/4l85 in a 69 Camaro with Street and performance plates on the motor. I used the G force cross member and it fit, the only problem is it hang pretty low and I had to make a spacer to make up the distance to the trans mount. If you aren't lowering the ride height it should be fine.
Here is what I have between my G Force cross member and the transmission mount. (That's a 2x4 on the flat) I could also use more room to keep the 4l85 lower in the tunnel. I need room for a connection on the drivers side.

I have new solid aluminum body mount bushings that are stock size. I did replace the the floor pan with a one piece so that could be the issue if it was not stamped high enough. I have the cutoffs in the garage so I can measure the height if need be to try and help you out.
Thanks for sharing your experience. For my knowledge, is the body of your car connected to your subframe with stock-height body bushings in good condition, or have your floors been replaced? You are the second person I've seen that has posted a report of not enough floor clearance over the top of the crossmember in the 3 years the Hooker 4L80 crossmember has been available and I would like to identify the source of the issue if possible.

I experienced a similar issue a few years with the Hooker exhaust system for the same application. The muffler hangers in the exhaust system attach to the oval shaped seat belt bolt gusset plates welded to the floor and the orientation of the oval gussets in aftermarket replacement floor in the users car were 180 degrees off from the factory position...that was a head-scratcher that took some time to figure out.

Thanks for the reply. Quick question for you, I have the headers from you guys as well designed to work with the system. You don't by chance make a 304 SS 3" pipe kit for the 67 that will work with the Ridetech G Bar 4 Link do you? The fuel tank is a Ricks Restomod that has the clipped corners for additional clearance.

We designed the 3" Hooker system to be compatible with the stock leaf spring suspension only as the abundance of available aftermarket rear suspensions made it a difficult task for product management to decide which one(s)to provide compatibility with. I'd like to revisit that application again in the future and provide specific coverage for some of the aftermarket suspensions such as the Ridetech, but the ROI is a gamble.
