Need advice...drop coils or cut stock coils???

[valero]

whats up guys...lookin to do a 1" front and 3" rear drop on my 63 c20...should i go with the cpp 1/3 drop coil set that i found on ebay for $190, or is there a way i can save some $ and (safely) cut my stock coils to fit this drop?? unfortunately, i dont have a lot of room to work with and i havent acquired many tools yet...so i gotta do it ninja style...lol

let me know what yall think...thanks!
