I'm having a hard time finding these NEW. There seem to be a ton used on fleabay, but I'd rather have new.

I used them with the Pheonix/Citation springs I use to use... from an old post of mine....F body isolator, part #10290379.

Thanks, I actually did search, and saw your post, but missed the part number. They're still discontinued, and it doesn't look like any in the aftermarket did polys.
I've been playing with the Moog chart, trying to come up with something. Since I now have airbags, I need to maintain a certain I.D.. So, I don't know if the 5659s will fit the bags.

I currently have the 6319s, but am looking toward something like the cc255

I had the 5659 springs (Phoenix/Citation) and there is no bag that fits a 5.0" spring. The F body isolators only work with a 5.0" spring. I have the 5609 spring which does fit a bag, I had the 5613 spring but that didn't drop the GP enough

 

[fleming442]

Why did I think this would be easier? The squared end springs don't seem to provide anymore than a .75-1" drop. I can get pigtailed both ends that drop it more.

 

[pontiacgp]

One other thing the F body isolator does is raise the car about 3/4" due to it's thickness. The mistake I made was thinking the F body isolater would work with an plain ended spring allowing me to cut the 5659 spring, the isolater works with a squared end

 

[fleming442]

It's looking like a Jeep TJ (3229/3227) is the hot lick for 8" installed height, which should be about a 1" drop and no isolators. Them things is pricy new, though. They may have to be a junkyard run; of course, can't find any TJs in the junkyards...

those spring have a spring rating of 200 that is kinda high for a G body.....

SHHHH, they're going in my 67 a-body.....
They're only 80lbs stiffer than my 6319s. If not for their price, they might be a good cheap (-ish) lowering option with an 8" installed height.
