Just wondering what people have paid to have housings machined to accept a larger wheel. I'm more curious about the rear housing, but would be interested to know if there is any price difference between front and rear housings.

anyone? lol i want to put my TA45 housing on my GT4202... could anyone at least tell me some places to call? i want to know what prices people have paid so i can tell a good deal from a bad. some say 500 some say 100...
