33-19.5 -15 Mt tires with corvette IRS help

[poorboiz]

OK I want to use MT 33-19.5-15 tires with my vette IRS. I know this can be done but not sure on wheels and any mode needed. I have seen a truck at one of the car shows that I went to that was like this. The bed on my truck measures 75 inches and I mocked up the tires and wheel that i have which are 15x14 5 1/2 inch back spacing and it put my track width to 79 inches, it is a stepside bed any pic or info would be awesome thanks.

Update I junked the vette rearend and im going to put a frankland quick change diff that I have.

That probably a smart choice. The Vette IRS could be made to work, but it would require a lot of effort for minimal return. If your set on the Pro Street look, at least consider the 20" wheels to give it a contemporary look.

The only thing I would add,... BUY your wheels and tires BEFORE you narrow the rearend.
Actual wheel and tire sizes are different than advertised sizes.
Place the wheels under the bedsides.
Allow for some side to side movement while driving.
Measure between the wheels for your overall rearend width.

Thanks for the info, I already have everything Im going to use all I need to do is assemble the truck!
