The Viking kit I ordered is for a GM "A" body, '64-67'. The springs in this kit are street springs as I'm not racing and or auto crossing. I think you can get it with either regular or big block springs, depending on your motor. I am using my stock A arms and not replacing them. On the rear setup, re-using my original stuff as well. Already boxed and new bushing in my 4 link a couple of years ago and all are still in great shape. The main reason I am doing this is for stance and ride quality, the rear coil overs come with a two position setup for the shock, then you can adjust away to fine tune it after. The front I'm looking at dropping an inch to 2 inches and that is enough for me.
I ordered this kit through a local Resto shop, who are a dealer for Viking, and they ordered directly from Viking, so I got the dealer price which is nice. Remember, up here we have to pay tax, import duties and exchange rate on the dollar, so it adds up.
I'm away from home right now for work, doing training for a customer who just bought new Co-gen generator system, from my company, We're a CAT Dealership, so when I get back home this week, I'll find my order sheet and post the details.
Joe.
