Ebay crossmembers

The cheapest way would probably be cut out a notch on the driver's side of your factory crossmember and weld in metal to reinforce it..
Plus you know it already fits your car without other modifications

I agree. I was told to do it this way over 30 yrs ago from the guys at the local speed shop. There were no fancy X-members available back then.
That's what's in my car now. I do have an extremely well made Iceman X-member awaiting the 200-4R installation.

Can confirm- My El Camino came with that modification, although it was done poorly and the crossmember flexed prior to me fixing it. Some thick bar stock is advised as opposed to rebar.

I had the Jeg's crossmember when I had my TH350 in the car and was very happy with it but switched to the Summit copy of the G-Force crossmember when the TH400 went in. I am very happy with that one as well.

My cutlass has the g force th350 and it fits great. My monte has the jegs th350 and its fit is horrible. Had to use 5/16 bolt to install as the holes dont line up enough for 3/8 and the humps are small and dont line up with my headers

The G-Force/G-Force copy does allow for bigger and better exhaust placement.

I just used offset header extensions on my Regal, worked fine and lined up with my existing exhaust.

When I used the Jegs TH350 originally on my frame I was able to use 3/8" bolts but had the slight clearance issue with the Pypes kit, '70's A/B/F manifolds, cats & Flowmaster down pipes. Even the new one I get for Jr.'s car can use 3/8" bolts. Now with the G Force TH350 I had to do a slight angle adjustment on how the down pipe/cat combo runs on the passenger side. Now I'm guessing I shouldn't have this issue on Jr.'s car using the Jegs kit, stock manifolds with Pypes down pipes & the cats.
