Fly wheel thickness?

[jasonL78]

Ok guy's looking for some help. I am in the middle of my motor swap and I noticed my ARP fly wheel bolts had some scuff mark's on them? So I looked at the clutch disk and all the spring's were hitting the bolt's that hold on the fly wheel. So I am looking for the stock thickness of an 11" fly wheel. The one I have is a hays steel 11" fly wheel that i bought used the part number is 10-130. It was supposed to have only 5,000 miles on it. It look's like new but I am questioning the thickness? I took a couple of measurement with my dial calipers I don't have a set of mic's and I came up with .932-.938 of an inch.

Thank's Jason

What flywheel do you need??? Crash

[jasonL78]

Not really sure what part number I need but it is for a 68 L78?

The original flywheel is casting number 3789733 and should be dated before your engine assembly date if the date matters.

What is the difference between the 3789733 and the 3973456?

[68SSCamaro]

I'm not sure what the difference is. I have the '456 flywheel in my 68 Camaro right now. The casting date is later so it replaced the '733 for some reason.

Well thanks everyone who helped out. I have found a 733 locally and it is date coded for my car.
