if your building on a budget the s10 frame works with little modification. they have od gears and are narrow. the kick up in the rear is a little forward compared to the stock frame. worth looking at. i am currently building a 46 sedan on an s10 but i am shorting the body 7 in to fit the shorter s10. the longer frame can be shortened. i hope to fire on it next week and will have pics of the build on my web page. let me know if i can help.
