shocks for my lowerd 79 k5

[BIG_J]

i so far have only lowered the front, and the stock shocks are bottomed out, stopping it from going any lower. i have 3 inch lower springs in the front and a 5 inch flip kit in the rear but with 2 inch lower shackles to make it only 3 inches lowering in the rear. what shocks do i need? im trying to find what vehicle had about 3 inch lower shocks stock that will fit because i dont have alot of money, or if there is a place that builds them just for this, for kinda cheap, thanks, John.
