Mustang II 141 tooth flexplate
I recently traded my cafe racer for a 1962 Fairlane 500 4 door. I received the car with the drivetrain out, an original cruise o matic 2 speed, a C4 tranny and a 2500 KM rebuilt mustang 302.
When I attempted to fit the drivetrain, my flexplate was too large for the bell housing. Which was weird, as I know i had the smaller of the two flexplates availabe for that engine/tranny combo (302/C4), the 157 tooth plate. Well, a bunch of frustrating research later revealed the existance of the Mustang II reduced size bell housing, that needs to be paired with a 141 tooth plate. That was only made for 3 years. And that is only occasionally supplied by the aftermarket. So, before I pull my hair out and search down another C4 in standard configuration, I thought it prudent to tap the brain trust here and see if anyone might have a source for the 141 tooth flexplate. Fingers crossed! I do want to use the Mustang II C4 if i can, as it has a higher stall Tq converter, and i already have it on hand.

And.... they have no Mustang II parts. Buddy has no idea as to where you could source one either....
Good luck with the hunt! |

It looks like ATP and Pioneer make or have made them.
Maybe just whack 16 teeth off of the one that you've got with a hammer?

Lol, i did think of that.....
Yes ATP and Pioneer are the guys, just very spotty production. I am going to reach out to Pioneer directly, all their vendors are indicating up to 6 month lead time.

Isn't the bell housing separate / unbolt from the trans?

The bell housing can be changed yes. The cost of changing the bell housing and procuring a torque converter makes it unappealing. Basically I find the flexplate i need or a different transmission, those are the economical options. I would like to use the one the Mustang II one if I can, due to the higher stall tq converter and the extra room for routing the exhaust.

Yeah, if you could find a flex plate for $40-100, that would certainly be cheaper than a bell housing and torque converter.

Yeah, i have never seen a GM unit with a separate bell housing.
The car won't see the street until summer at the earliest, looks like I will just have to wait out the lead time. Summit is showing it will ship late december now, so already much sooner than the first lead times indicated.

Looking at car-part.com. Some sources show new, but they may have them mis-catagorized. Try Allied Auto Parts, Ltd. Can-MB(Winnipeg) 1-888-233-3332
Sherwoods Auto Parts Can-BC(Port-Alberni) 250-723-7222 / 250-724-1021 Or if you want to try the US then St. Francis Auto Wreckers, Inc USA-WI(Milwaukee) 414-481-4540 Lambert's Used Cars & Parts USA-TN(Selmer) 731-645-9634 / 800-325-7443 There's several others listed on the site if those 4 don't pan out. |

A transmission rebuilding specialty firm? Meaning, they may have sources you are unaware of...
