I have a 89 indy 500, I was going to put in the xtra-10 but found that my tunnel and belly pan were trash. So I started looking for a new chassis and decided that I should by a chassis with xtra-10 in front and back so i'll have xtra-10 all around. I was wondering if how close where the mounting spots, and what else would I have to modify? Would it be easier to put the motor in with the xc oil lines, coolent lines, brake etc. or use everything from the 89?
