I have their 41-48 kit under my 41. Good quality stuff. Look about half way down the page.

You meant the center bolt that holds the spring together..??? if there is no hole in the spring perches that you have..drill a hole to clear the bolt..Then you can use the springs that you have..

Yes, Because of the torque tube style rear that was in the car the center bolts are too far forward. If your new perches are long enough just drill a new hole in the right location. If they are too short make some new Perches out of right size box tubing and drill holes in proper location. You will also have to drill matching holes in the Ubolt plates. Hope this helps.I have done this and it worked great.

You can re-drill the perches. However, the stock springs were designed only to hold the car up. The torque tube transferred the rear end torque to the chassis through the transmission. Without the torque tube, the springs are now going to transfer acceleration and braking torque to the chassis. The original springs are narrow and were prone to break even with the torque tube. No torque tube plus a higher horsepower engine plus better brakes equal broken springs. Now I know my saying this is going to bring out all the 454 4 speed guys who have been running the stock rear springs for 50 year without a problem guys telling you how I am wrong about all this. Bottom line, if you are on a tight budget, re-drill the perches. If you want peace of mind, put on more modern, wider springs.

I do belive chevsofthe40s.com has a replacement spring set that is wider than stock for that very reason. the stockers are weak. I have a '51 w/ 235/PG.

I merged your new thread with your old thread about this car & rear differential.

Do you know what a torque tube rear end is? this car should have one

You must unbolt the drive / torque tube from the trans to remove the differential from the car. IF the trans and engine are gone , half the work is completed to remove the diff

It is best to have the leaf springs unbolted at the rear of the springs to slide the diff and torque tube out of the car.

Unbolting the tube from the diff is too much work under the car IMHO.
