motor mounts, steering linkage depending on the column u use,lower rad replacement brace,hardware, find a brake pedal and bracket, do i need to go on. i had to fab or scrounge a lot to get the other stuff i needed. i modified the s10 wiring to work in my truck to save some money. the ez kit is worth the price it is well enginered and i talked with the owner and he is very nice and know his stuff. an will help you with any questions you have. just go on the two sites and look at the two kits and decide for yourself.

i not knocking the ad kit it is good if you don't want to use all the stuff of your doner s10 that you can,but it is up to you the builder to decide the best route. like i said befor if i had to do it over again i would go with the ez kit. thats just me though.
