Just about to do another FMX / FOM conversion. I have to ask a question ??? Is the input shafts the same on early 54 FOM as late 57 ??? I sold the 2 spare  late model FOM I had ,now I need the front shaft from one . A mate has an early 54 auto that I can have .Just want to make sure before I send them off to be rebuilt .I have a late model convertor and a front pump . Still chasing a late model flexplate .

Thanks Bill ,

If it turns out the early 54 is different I will buy the shaft from you . Flex plates are hard to find . When I do find one I am going to approach an engeering / laser cutter  shop to see what the cost is to have them made ???? I don't think I would have any trouble selling them .

Hey Lon, I have one left, I don't really want too get rid of it. But if you want to have it reverse engineered, I will be glad to loan it too you. I think that Mac's has the std shift ring gears, so it should not be that hard to make something like the Flat o matic C4 flexplate.

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 .

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.

Dennis Carpenter sells new ring gears for the automatics. Auto's use a 146 tooth ring gear; part number EAA-6384-A USD $20.00

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.

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

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.
