Rear springs are worn out & the back is lower than the front. I previously owned a 64 tempest and used 64 lemans station wagon springs to set the rear a bit higher than the front. Will 70 skylark wagon rear springs do the same thing for the 70 skylark convertible? Anybody have some suggerstions? The parts guy lists all kinds of different springs for skylark, gs, sport wagon, etc. The front springs on the car are new, but I am pretty sure they are drop springs of some kind since the crossmember is only 3-3.5" off the ground and I am thinking about just replacing all 4 at once. Reaon I asking is I went through 3 sets of springs on an old 71 firebird I had with a 400 in it and ended up with straight 6 a/c springs to get it right, it was great! not.:spank: Thanks, John
Hello, All i can say is that the front springs will settle I have a set of 70-72 coil springs for the rear that are powder coated but are not right for my car. ill send you a pic of the car they came out of i think you'll like them if your interested.
all springs will settle. 70's buicks always had a low look to the rear. your best bet would be to contact espo for springs and what your looking to do.
The correct ride height figures for the car per the Fisher Body Manual call for a nose high stance. It's also in the Service manual. IIRC, it is @ +1.50" from front to rear and is measures at two specific places along the frame rail that are approximately at the fender to door gap and where the rear lower control arm connects to the frame..... I'll check. Page 40-8 or the 1971 Service Manual has it as four separate measurements. Figure 40-3 "trim Dimensions" Hope that helps for a starting point. From there you can modify at will.
Little late to the party but despite how Buick set these up, I've always felt these cars look best with a slight rake to them (top of door just about level). The factory springs are nice for ride but kind of sloppy for handling...looking into that now.
Actually on a GS heavy duty springs were used on the front but standard springs were used on the back. You can see this if you really look hard in the assemblay manuals spirng charts. I guess Buick wanted a nice smooth ride.
