im new to this whole fixing blazer up thing so im going to need some help. i just got a 74 k5 yesterday and its in need of alot of body work. the front fenders and hood i know i can replace(thats easy), but for the rear fenders i have no idea what to do /forums/images/graemlins/1zhelp.gif. they are rusted allmost all the way around the wheel wells. the rockers are rusted out but i have allready have made plans to put sliders in instead of replaceding them. so how do u fill the rust holes with out replacing the rear frnders?
