9 leaf is a stock spring, 7 leaf is the heavy duty gymkhana spring and I've never seen a 10.

I'd strongly suggest a single blade fiberglass spring. VB&P is no more, so I can't recommend what I have, but I'd start by calling Van Steel, after searching this forum for other similar threads. 300 or 330 lb, probably, based on your shocks as much as anything else, but please don't take my word for the number.

I am in the same boat so to speak...my cars previous owner put spacers in to compensate for the bad curve in the rear spring and it really needs replacing. Since I am just cruising I think I will stay with the stock 9 leaf type. The added bonus is that this version is much cheaper than all the single leaf and higher tension models.

After many changes, my '72 350 TH400 automatic performs to my satisfaction with a 330 spring and Bilstein HDs.....

Thanks all for your time and help, been reading up on this. Found a good deal for a new 9 leaf (6/3) spring and I'm gonna give it a try.
Again, thanks all and I'll post how it goes once I get it installed.
