... Advanced Design body on S10 runnin'gear, they do that, but seems I usually see folks try to use the whole chassis from the long wheel base S-truck, though I am not necessarily advocating that. Are you planning to retain the original front end? What transmission?
To browse and find earlier discussions, go back to previous page and see that pull-down box at upper right, "Show topics from last (# of) days," and also look in "the lounge."
Best of luck.
