Here is a picture of the new floor and trans tunnel in my 1200 sedan. The floor board was rusted out on the passenger side so a whole new floor was fabed out of 18awg steel. Also had subframe connectors made out of 1.5x1.5 inch 120wall square tube. The connectors are welded into the original subframe they continue back and tie into the leafsping brackets. The new transmission crossmember is tied into the new subframe. Should stiffen the chassis really good.
The trans tunnel as been sectioned 9inches to clear the ca18 tranny and rewelded in the back a new piece has been fabricated up front to take up the gap.
Here is a pic of the b210 brake booster and relocated clutch master to make room for the new turbo manifold. Never mind the brake line sticking out there all getting removed and new lines made.
Sorry about the quality of the pics they were taken with my phone.
