58MM TB BELLOWS
Can anyone tell me what bellow they've used when changing their stock TB to a Holley 58MM TB? My stock one doesn't seem to fit and I can't find anything on the net about it. I can't be the only one with this problem?

Re: 58MM TB BELLOWS
58mm TB should be 4". A round 4" coupler should oval out enough to fit, however my stock Camaro intake fit my 58mm holley just fine? Granted it was tight and I had to stretch a bit but it went on.

Yup, its very tight, use a dab of oil on the T-body so it'll slide on easier. Also make sure the clamp is super loose..

Just sent TB out to be polished. I'll try it again in a couple weeks when I get it back. Thanks for the info.
