Hi Dave, The can is going under the exhaust manifold but wraps around on the intake. It really should turn under I may mess with it again someday but it's running great and I live in the south so I'm not driving it when it's below 30F. The intake tube is just laying off in there but it seems to be getting enough heat.
On the seat cover I got it from Raybuck Auto and body parts. for 225.00 It comes with the hog rings and pliers. Material is Velour and vinyl around the sides.
The floor is Vinyl I got it from Stockinteriors.com it came with the insulation pad for 171.00 with shipping.
This is the insulation that I used I've seen were other people have used it and worked well. Got it from Amazon around 23.00 I used 3 rolls.It was very easy to mold into all the crevasses. I bought a little roller and it was kinda fun to put down, the vinyl not so much. Big bulky and it is oversized a little so you have to trim it.
