does anyone know where I can get a 3.5 vband flange and clamp at a reasonable price?

I got all my stuff from www.atpturbo.com

Take your old one down to a diesel truck parts place and ask them to replace it. I bought one this way for $40. Big trucks use the same stuff on their turbo exhaust. Same one from an import car parts company wanted $80. Not all v-bands are the same width and pitch across the band, so keep that in mind. You can't just order a 3 1/2 in and expect you'll get the right profile for your flange. Get part-number off the old band and give that info along with diameter. Good luck!
