Technical backing plate ID thread

I'm afraid that QC and my bank account are just not ever going to be compatible.

However, pix when done will be appreciated by all.

 

F-1 and F-100 backing plates are the same. The hubs are different, with the F-100 having 7/16" less offset. The drums are also different for that reason.

 

F-2/F-250 brakes commonly used with Buick finned drums

 

Circle 4 Racing aftermarket brakes; similar to Lincoln Bendix brakes.

 

F 100s are 11”, aren’t the F1s 12”?

Anyone recognize the backing plates on Joe Wilhelm's "Wild Dream"? This says '58 Buick but they're not. I have '58 Buick.

 

Trying to identify these backing plates... hubs are wide 5's

 

'39-'41 backing plates; being they are wide fives; probably '39. Probably made that trailer out of a '39 front axle.

 

Thanks @RICH B ! that's good news...first year for juice brakes!

 

I just picked up two frames with full suspensions. I was told one was 39 and one was 37....... any help confirming what I actually have would helpful.

 

Top looks like 36, bottom one 37-38.

the round back spindle with cable brakes is indeed 37, the square back spindle would be 35 or 36

 

These are wilson welding finned backing plates. I have been told that they use Buick guts but I cannot confirm that.

 

thanks guys for the response!

 

I've been thinking a lot about backing plates lately. I don't need to find/buy any or sell any; just doing a lot of thinking.

Anyone got more pix they can throw up here along with pertinent information?

 

buick backing plates, year unknown (to me)

 

I know, right?

 

One of the many reasons I've been pondering this lately. I think these are 40 Lincoln backing plates with holes and SS screens; anyone confirm this? Whatever they are they are just WAY cool. I probably got this pic form the hamb sometime back in the past. Belong to any of you?

 

It's very interesting that there are only 2 bolts holding these on.

 

I guess I can't pin down the year range; but I've cut a few of them apart getting 45 fin drums off '63 & '64 Buicks.

There are three bolts, the top one goes in hole by the anchor pin and screws into the upright; that is the one causes trouble when the drum is stuck.

 

Interesting that it is mounted upside down. Went to a bit of work to do that.

 

I'm seein' self-adjusters but not E-brake, so I'm guessin' these must be fronts.

 

Good eye; I had never noticed the upside-down.
