V band flange sizing question
the kit i purchased cam with a MPT-70 with the V band down pipe flange. well i found a great deal on a polished Turbonetics T72 and deltagate that i could not pass up. thing is, the Vband on the turbo is about 1/16th to 1/8th smaller than the flange on the down pipe. should i
1: grind the down pipe V to fit the turbo?
2:attempt to find the other half of the turbo flange, and have it welded to the down pipe?
3: cut both off and just have new flanges welded to both?
the turbo's flange is 3 5/8" from top to bottom.
