I only had 2 responses. I'm not saying they were bad ones or anything, but I think all the testing posts didn't allow many people to see my post. I have a 164 tooth flywheel. I have a 70 (i think) 302, and a '68 bellhousing (I think its off a '68 302). A previous post said that all 302's came with a 164 tooth flywheel. So as long as my bellhousing is from a 302 it will work right? The National Parts Depot catalog says a 69 and up bellhousing is required for a 164 tooth flywheel. Was that just a typo in the magazine. I need to be positive before I want to get it all together. Thanks in advance. Justin

Have you tried a test fit? Once I bought a flywheel at a speed shop when I was converting my previous '65 FB from C4 to 4 spd and I put the new flywheel on the floor. Then I tried to place the '66 clutch bell housing over it. It didn't fit - the flywheel got in the way. The fly wheel was a 164 teeth unit and I had to buy a 157 teeth unit.

Hope that helps,

Who told you the 302 was 164 tooth? It should be 157 for a 10 inch clutch where as the Boss 302 (C9ZE) and 351W take a 164 tooth flywheel for the 10.5 clutch. Some of the aftermarked 157 tooth (like the steel billet I just got from McCleod) can accomodate a 10.5 inch clutch. There are two bellhousings, one a bit bigger to accomodate the extra diameter of the flywheel itself. I know my C5AA which is corect for a Boss 302 accomodates the 164 tooth flywheel. What is the casting on your flywheel and I will look up in my master Ford book for flywheel match...

Hey bosscars, I answered his post before with information from an interchange I have(not ford) it lists the following for 68 Mustang 302 bellhousings:302-2V = C5AA-6394-A, cast aluminum, Mustang(including GT 350) 302 4V = C5AA-6394-B, cast iron.Same interchange also lists all 68 Mustangs with 302's recieved the 164 tooth flywheel.The 289's used two different bellhousings(according to this book) they were the old familar C5D6394-A before 2/15/68 and the C8ZA-6394-A after, both utilizing the 157 tooth flywheel.I have the C5AA-A aluminum bell on my own 66(took it off a 302 in a Fairlane at one time)with 164 tooth Ford flywheel and 11" clutch. I think that if you/he have the bellhousing and flywheel off, as mentioned by someone else above, the easiest thing to do would be see if the flywheel fits, a 164 tooth one won't fit to well with a small bellhousing.Would I would like to see cleared up is the various early 289 flywheels, I have seen numerous casting numbers and teeth count.Most people seem to say the 157 tooth is the correct count for the C5DA bell, but I have in front of me now, a January 1965 edition of the Ford Car Parts and Accessories Catalog, it lists the following flywheels and descriptions for the Mustang:part number C4OZ-6375-A for the 260 engines-160 tooth ring gear, for the 289 (non hipo) it lists the C3AZ-6375-F, but does not describe further, for the HIPO it lists the C3OZ-6375-C,used with C3OE-6380-B ring gear, but gives no description or listing of this part number.Under ring gears for flywheel in same Ford book it lists:for F special,and F,X 2/B and 4/b 289 a C2OZ-6384-A ring gear-described as 160 teeth, 13 1/4" O.D..I realize these are the box part numbers and not actual numbers to be found on parts.But it sure looks like they were talking 160 not 157 teeth in most instances, I have some of these Flywheels, but I have never sat down to count all those teeth, someone here did last week, and they found an original 289 flywheel they had assumed was 157 teeth, and it turned out to be 160 teeth ! I sure wish Bob Mannel had included flywheels and bellhousings in his book !

Somewhere I read that some '65s had 10.5 inch clutches while they went to 10s in '66. I also heard of an 11" clutch for the later years but not sure when. You might try asking on Mr Fomoco's site. A lot of tech heads hang out there.

If you have a 164 tooth flywheel its probably for an 11" clutch. You need to get the bug cast iorn bellhousing. Thats what I had to do.
