I made a wooden one a while back, but I messed up one edge while sanding.
I had a spare TB & intake sitting around and put it on for a test fit. The corner wasn't sanded perfectly flat so there was a very small gap between the wood and the intake surface at the corner.
But, I did figure that I could go up to 5/8" or maybe even 3/4" spacer and not have to replace the TB to intake bolts, which would be nice since I can't find any longer bolts locally (I haven't checked the Web). Does anyone know if the TB bolts for a auto and a manual are the same? My auto has that heater between the TB and the intake and it's about 1/8" thick.
I also rechecked my air intake tube to hood clearance and I think it'a about 1", maybe 7/8". I don't know how tight that would be with a 3/4" spacer and possible engine roll when revving :-/
I have been thinking of larger tires and maybe a BL one of these days which would make a 1" or 1-1/2" spacer no problem (if I can find the bolts or maybe use threaded rod as studs).
Anyway, I probably won't get back to this until I make the decision on the BL or I just get tired of waiting for myself to make a decision and make another one (a little more carefully this time)
