front coil overs on stock k frame

i forgot to mention my afcos are 3850s with a 300lb 10in spring, a 250lb spring is what i had ordered but for some reason they shipped a 300 so i put it on and it seems fine, i also could go with a 12in spring, also im using Bobs Pro fab parts and i cut the lower mount and moved it in 1in to straighten the coilover, id highly recomend his lower control arms if your going coilover, if your useing the stock upper mount it is heavy metal but still needs bracing because of it design. mine is all aluminum motor so if your using an iron block then a 350lb spring would be a better start.
