So- if I understand the one on the right is getting hard to find. What is a good one worth?

It would be the one on the left.The one on the right is the early style available as a repro from several suppliers 

  

Bill:

I just counted the teeth on the 58 auto flex-plate for V8's and they are 148 teeth. You are correct in that the ones carpenter is selling are std trans ring gears or 6 cyl automatics.



thanks marv



This appears to be the correct tooth count and diameter. I will mic a flex-plate in the morning for more info.

Thanks Glen, i will copy the photo for future reference  Carl

I've had a couple PM"s about the difference in Y block flexplates, so I though I would post a pic on Lon's thread.

The one on the right is a 57 and the one on the left is 58 and later. Hope this clears up some questions for some off you guys.

Marv, i,m 100 percent sure they are std trans ring gears, auto trans are more teeth on bigger diameter and a lot thinnner,

Lon: RE auto trans parts; might try a guy in the eastern states, name is Edwards, sorry can't find my full info, but apparently he has a warehouse full of vintage auto trans parts. May have Flex plates? Try Hemmings or maybe someone here can come up with an address etc.

Lon, its allways hard getting something remade in limited numbers , especially here, i have had some things done over the years, but majority of others were just out of the financial question. I hope it works, regards bill.

Glen ,

Thanks for the offer .Doing a bit of research at present on getting a ring gear laser cut. It then has to be heat treated .I can also get the centre section of the flex plate laser cut . The problem is having the centre bit pressed so it has all the factory lumps & bumps in it . Than the whole box & dice has to be welded & balanced . I will keep you posted if I can come up with a reasonable price . Don't think I would have any problems selling them ???

Lon

PS . Good luck with Columbus ,whatever way you decide .
