it wasn't so much that i had already drilled the body, but i had already cut down the body posts, and to get them off i had to take the shocks off. Also because they were rear posts, there were no holes for the cross bar. Just a bit of a hassle. It fits ok now, i'll definately post some pics when its mounted.
wallot, thats a great idea mounting the single post in the middle of the DUH tower!
