what parts/kit to static drop 1972 suburban

[gatch]

Hi i just bought a 1972 suburban. i have a 1963 c10 that is static dropped using all parts from cpp. I used the mcgaughy drop spindles and 2 inch springs and 2 inch front springs. i used 4 inch rear spring with 1 inch block on back. I would like to have the suburban sitting lower in the front.. Do i buy a kit from ece, buy 3 inch drop spindles from belltech and run 3 inch front spring on suburban? i want to run 20 inch ridler with 4.75 back spacing? please help
