My wife's first gen has one... the vertical brackets pretty much touch the floor but I think this may have to do with the half height body bushings. I plan to eventually replace this crossmember because I don't like the amount of flex it has.

Yep, my mistake.

I hoped so, but I have seen installed photos on the 1st gen and this is how they are oriented. Ben also has pictures posted in the new 2" header post as the same orientation.

Guys I really need some help. I recently got word that I'm going to be transferred and I don't know what to do for an X-member now.

Probably too late at this point, but today I just dropped the body (69) onto the DSE subframe with motor/trans installed. The brackets on the ATS crossmember are up against the floor. I have the DSE std height mounts. Tim- what trans cross member do you plan to run on Deb's car?

On a second note- I used the 1" setback mounts, and the 102 FAST intake is against the firewall. So I dropped the sub back out for crossmember and engine stand replacement ...

the ATS one works perfect

The mounts are supposed to be up at the floor. there should be 1/8 - 3/16 gap but that is all.
Just re red the OP first post and the car is a second gen so that is probably the issue the AST Cross member shown a couple post back is a first gen X Member and the second gen has a different shape floor and the side brackets are shorter. I an thinking that is where the confusion is.

I have the ats x member and the brackets hit the floor on my 69 w DSE subframe, just as Tim mentioned above on his wife's car. As I was tightening the subrame bolts, they got tight & I noticed the brackets up against the floor. Stock height DSE body mounts. Maybe I'm missing something...

I think part of the confusion comes from DSE saying their second gen subframe uses a first gen crossmember. At least that is my understanding.
