66 barrracuda/valiant guys

looking to see who is running a 6 inch wide rim on the front,,,your back space and tire size please,,

im having wheeels made,,orignal correct spoke torque thrust style,,

because of my wide rear tires, i need special back space,,and finally found some one that will build them,,,

but there front rim sizes are a toss up for me,,,15x5 wide with a 3 inch back space or 6 wide with a 3 3/4 back space,,

i currently run 15x5 with 3 1/2 back space,,

im going to spcace my rims out to see what they would look like at 3 inch back space,, with the back being tubbed and tires tucked inward,, im afraid the 3 inch back space will make the front end look wider,,

and the tires on my front now are almost VW size,,, 165/80 r 15

thanks for any replys
