Looks great. I've now done that to three TRs. The toughest part is getting that dash saddle to go back over the hump. It's as if back in '62 they had a special computer that calculated the precise curvature so that the four bolts could reach the captive nuts only in one precise location, at one exact angle, and only then without cross-threading or stripping the bolts.
The insulation does look great. Heat and sound.
Is that Eastwood product backed with a thick matting?
