i outboarded the front springs to center the axle up i think its a 34 1/2" outside to outisde. I upgraded to a corvette M/C ( 1 1/4" bore) and made a simple adapter plate out of a piece of 3/8ths plate. and put studs in for the chevy m/c and drilled holes for the toyota booster. For the lines i got some stainless steel braided lines from Bones on pirate and they hook right up to the toyota lines. but for the M/C i got adapters to go from the M/C to 3/16's and i reflared the hardline for them. works great
