Most practical/cheapest way to raise the rear
So, after a series of events, my 77 Vette became my daily driver. It desperately needed a set of tires, so after much reading, I decided to put 275/60/15s on the rear.
Unfortunately They rub just ever so slightly whenever I hit a bump, or pull into a parking lot. After looking underneath, I discovered that all the bushings on the rear spring bolt are toast. I thought I'd just tighten the nut to lift it temporarily, but unfortunately I had no thread left to do so.
So, I need to know the most practical, cheapest way of raising the rear. I don't want to just shim it with a ton of washers, but I don't want to replace a whole lot either. I have yet to look at prices for the bushings, but I'm sure someone here can point me in the right direction.

I'd get rid of the oversize tires that are causing the root problem and change the bushings that are worn out.
Trying to use a 36 year old car as a daily driver comes at a price.

Check the length of your bolts. Originally they were 6"- could have been changed to 8" or even 10" to lower the car.
If you need - I'm sure I have a couple sets of 6" bolts laying around.
Just PM me if wanted/needed-

Hi A,
Installing a new set of bushings will raise the rear ride height even using the bolts that are there.
The new (thicker) bushings will effectively shorten the bolt!

That looks like a pretty significant difference! I only need at most 1" more clearance. It's raining out right now, so I'm not crawling under the car to measure the bolt, I might melt.
