spring information needed!!

Hey guys not posted anything for a while been in hospital. Started lowering my c20 burb and ran into some problems... First I had a heart attack (not while working on it) few days in hospital stints put in and off work for a little while but doing better never dreamed of this at 48 years old but that's life. Starting to work on the burb again but slowly. It has trailing arms so I have everything lose was going to cut springs but if I do they are not going to fit back in "socket" plate to bolt back in. My question is will front springs from a c10 or c20 work on the back? I have a set don't really know if they are front or back springs. Want to lower back 5 to 6 inches also adding 2" drop blocks. Thanks guys I need some help on this one also trying to save a little cash since I had the extra springs.

Simple answer is don't do it. Back spring radius/size is different from the front. Be safe and spend the $100 on a nice set of rear drop springs. Just my $.02!

I agree with 4shongo. The rear springs are tapered top and bottom so you can't cut them. The fronts will not work because they are not tapered on either end. I also don't think you can go that low without "C" notching the frame. Do some more reading on lowering limits and frame mods. Save your pennies and buy some springs.
