hmm...I surprised the frame doesn't come with them if that's the case. $7750 frame, engine mounts not included, but required lol. :G-Dub:

They will be other trinkets you'll need as well...... rack fittings to connect the ps lines, headers, trans crossmember...etc.

I'm sure hoping the headers I currently have fit. What do most folks use for the tranny X-member?

I'll be surprised if your current headers work due to the steering shaft going to the rack, the shaft is closer to the center of the car than the stock shaft would be. The DSE headers have a space for the steering shaft to pass between 2 of the tubes.
My cross member is custom made, you may be able to modify your stock cross member and use it but I'm not sure.

SOB....I just saw your pictures of the headers. I'm guessing another DSE only part....Crap I should have thought through this DSE frame a little more.

I used the factory 1st Gen SBC motor mounts with my 1st Gen DSE sub frame. I also found that DynaTech headers fit and clear the steering column nicely. Speaking of steering column, you can buy all the necessary parts to fab your steering linkage from Summit. You will probably need two u-joints and a section of 3/4" DD shaft.

DSE headers only work if you use the setback mounts. Otherwise you will have to source headers. A number of guys are running the Ultimate Headers. Very nice piece. They are not full length but no clearance issues. Dont remember what trans your running but if it is a 6 speed get the ATS crossmember from Speedtech.

You don't have to use the DSE headers necessarily, in fact it would likely be cheaper to just modify the ones you have IF they don't work as is. I would take any first gen parts recommendations with a grain of salt. I know for fact there's a big difference in the frame stands for the engine mounts. The engine is significantly farther back in a second gen vs the first gen. I would mock the engine, trans, and headers up in the sub before you put the sub in the car and see what's going to work. I have ATS tri-y headers on my wife's first gen which everyone told me would not work with the DSE sub but with a slight modification to one tube they do in fact work.

Which company makes DSE's headers? I already pinged SW and Lemons, neither confirm.

DSE builds there headers in house.
