Transition Camaro

[MX145]

While working on the floor I realized something wasn't right on the subframe. The seat pan frame bolt was off center with the floor section. I decided to pull the sub off and measure it all out. It came out within spec's but had some cosmetic damage due to a previous accident. Turned out the subframe was sitting crooked in the car. (Probably from the impact). My father and I straightened out the core support and the subframe to make it look cosmetically better in line with the rest of the car. I'm not 100% sold on it yet as I still have work to do on it. If it doesn't look great by the time I'm ready to do the coil-overs I'll look for another. It just has minor surface rust so it's worth messing with compared to what I've been seeing for sale in the local area.

Some of the damage is hard to see in the pictures. We tack'd a bolt to various points on the crossmember and used blocking and a bar to run a nut up against. We tightened the nut down pulling out the dent and hammered the bottom flange flat as we went. This 1/8 stuff took some time to move compared to 18ga. We also fixed the front crossmember that had a rise in the flange. I cut off the formed tie between the two crossmembers. This piece had the most damage. While discussing how to fix the formed piece my buddy Ron came up with a great idea of running a piece of 2x3 tubing between the two. It shouldn't look out of place with fabbed coilover mounts and some of the other work on the car. Hopefully I'll have some "after" pics to post soon.

I found some rust across the front flange of the inner seat pan structure. (The piece that the subframe bolts to). I cut off the rust, treated and primed the rest of it and built a crossmember to run between both rockers to give the seat pan a good support to weld to and stiffen up the car. The gap in the crossmember fab pic is the bad lighting and cell phone camera. I chamfered the edges of all the pieces before I welded them.

Since the floor was in I permanently installed the passenger side connector, seat pan inner, and outer.

The crossmember fits great at the same height as the finished seat pan and sits about 1/4" below the floor on the bottom side of the car. I don't like how high it sits in the middle but wanted to error on the side of clearance for a t56 hopefully in the future. After looking at it in the car I'm going to slice the center section and lower it about 1/2 to 3/4". The bottom will stay in the same location but the tube will be about 1 1/2 or 1 1/4"x3 instead of 2x3. This should look better and still be high enough on the front side for the new higher transmission tunnel when the time comes.
