Another small update. I went by the steel yard and picked up some 1.75x.25" cold rolled steel remnant and started working on the adapters to bolt my 94 seats down. I might need to counter sink the bolts in the rear if the new risers run into them. However won't know that till I get the seats back. I ended up butting the runners up in the back and then laying them over the front pieces. This is because the rear mounts are higher than the fronts by about 1/2" this doesn't totally get them flat again but is closer.
Also, the reason I went and picked up a second passenger seat slider was because my first one was dropping ball bearings and I wasn't sure why. Well, now that I have the new one I can see why. the slide rail on my original piece is bent to hell. Someone had too many Royal with Cheese and french fries.
