i'm trying to put the front axle from a 1968 Ford B500 (short bus) under a 1960 Mercury M500 short bus.

I'm having trouble finding front brake drums : Part No. B7Q1125A
Stamp on the drum reads: BUDD 84617
Are these the same as a F500?
The 1968 Ford VIN: B50CCD51289
Is there a disc brake conversion kit for this size axle?

-The 1960 Mercury short bus now has 500+ ft lbs of torque, 500+ hp in its stroked FE engine (390 is now 455 cu.in). The original drums and shoes on the Merc were Tiny, i scored the '68 ford short bus for a song, hoping to use it's front axle and larger drum brakes.

thanks eh

 

See post #3.

No Dealer or NOS company has any C3TZ1125M. C3TZ1125M was identified by Budd #95725 or Dayton number 03-120588. So you might call your local Napa, O'reillys, a-z, etc. with those numbers.
Note, B7Q1125A was identified by number 120704. Wrong muchacho.

 

El Jeffe: OP wanted B7Q-1125-A which was replaced by B7Q-1125-C then: D1TZ-1125-A

Also replaced B6Q-1125-A / See post #2.

 

True. But OP lead you down the wrong trail. In post #1 he said:

Stamp on the drum reads: BUDD 84617.


Budd 84617 is C3TZ1125B. Mixed with C3TZ1125M. EDITING HERE. Bill, if you catch this please post the 73/79 LT page I referenced in post #3 so OP can see it. Thanks.

 

I remember C3TZ-1125-M because Coberly Ford, then Crenshaw had the U-Haul account.

Both dealers had parts pullers, so I didn't have to heft those drums, they weigh a ton!

The brake guy at Coberly was nicknamed the "razor." He was harder than hell to get along with.

I found out a coupla years ago that an FTE SoCal chapter member married his daughter!

I edited (erased) post #2, referred the OP to your post #3.

 

Those part #'s bring back fond memories of when I was a school bus mechanic at 18 years old on some 68 through 72 b-500's through b-700's. Those were the days. Brake drums and shoes were much smaller then than they are today.

 

We're gonna need pictures of this monstrosity!

 

here's a video update of the 1960 Mercury short bus

 

and THANKS so much for your help! I appreciate it
