70 gmc lowering help!!

[belway]

I have just purchased a 70 gmc c10. I am new to the forum, have been reading up on different ways to do it, just wanted some input.

It has drum brakes and rear leafs. I am thinking of flipping the rear leafs, what i have read that gives me a 5" drop.

for the front i was going to keep the drums for now and put 3" drop coils in.
Any thoughts on this would be very helpfull thanks.
