Flexplate problem

My flexplate is worn out. I'm trying to find one that's 153 teeth and 15.5" diameter. I can find the right teeth count or the right diameter, but not both at once. Can anyone give me any info on a part number or where to get one of these flexplates?

It grinds sometimes when I start it up, so I looked at the flexplate and the teeth are shot. I pulled the motor and did some upgrades--rebuild, intake, carb, oil pump--and this flexplate is the last thing I need before I can put it back in. I ordered a stock flexplate, but it doesn't fit right, so I'm trying to figure out which one I need. The measurements are 153 teeth and 15.5" diameter, but I don't know what part number that is.

Sounds like they just shipped you the wrong one. Can you just take the old one to a local parts supplier and just ask them to match it up ?

flex plate

Hawkline, Be sure that you have the correct dust shield that centers the starter. In some applications the automatic cover is different than the standard. Also there are 2 different starter noses that Ford used which will cause flywheel problems. The smaller nose was for marine and industrial and sometimes ends up at auto stores. There is about 1/8" difference between the 2. Give this stuff a close look. Kenny

The Ford parts catalog only shows one flex plate and doesn't give any specs on it.
