While on Junk Jaunt over the weekend I ran onto a 1929 AA bevel gear rear end for sale. I know you don't see very many of these and I have always wondered why. Were they that bad? I know they were only used for a short time between the worm drive and the more common 30-31 AA rear end. Also was wondering how sellable it might be. Told the guy to let me know if he did not sell it. So I may get a call about it later this week. Rod

This is from Neil Wilson, maybe he knows why it was dropped so fast.
Bevel Gear Type Rear Axle 1928-1929
late 1928 through early 1929.
The July 24, 1929 Indianapolis service letters announced that the differential housing with “HS” for high speed and “LS” for low speed axle was being used for gear ratio identification. There was no indication as to where on the housing the stamping was located.

Thanks Bob. Will email Neil and see if he has some insight. Only the 3rd one I have seen in 30 plus years in the hobby. I won't say that I would have even noticed during the first 10 years. None of them were still attached to their chassis, which seems somewhat telling. One of the other ones I seen belongs to my second cousin and is laying in the grass next to his corn field. Belonged to my Great Grandpa. Rod"Much of the social history of the Western world, over the past three decades, has been a history of replacing what worked with what sounded good."

Need a little help for friend with a AA. See, he is looking at a few more MPH out of the beastie and called Mitchell and they can sell him the 'in driveshaft" 2 speed.
I remember in my youth a transmission of sorts that went between the 4 speed and driveshaft but really don't remember if that was just a PTO or an actual over/under trans or something of the like. Need info on what...07-24-2018, 05:07 PM -
I am getting my list for Hershey together and am looking for a speedo drive for my '29 pickup, which has a 3.54:1 rear end, so am looking for an 11-39 turtle. I have a spare turtle for a 3.78:1 rear end, 9-34 (a 19 tooth gear). I could simply buy the 18 tooth gear, but I expect it would be a smaller diameter than the 19 tooth in this assembly.
Is there a difference (dimensionally) in...09-04-2019, 04:40 PM -
1930 pickup came into a friends shop for some work and he sent the brakes and kingpins to me to do. Got the spindles all cleaned up and discovered the word "TRUCK" cast into one of the spindles. Never seen that before. This is NOT a AA. Anybody have input as to what? when? why?...11-01-2020, 06:39 PM -
Doing my research I have a 4:11 rear gear however I cannot find a complete speedometer gear case that has the proper 21 tooth I see 18 and 19 tooth for the 3:56 and 3:78. This means I’ll have to buy a new complete case and then a new gear to put in it unless someone can point me to a source with a complete 21 tooth assembly. Hopefully someone can help me out on this one. This is for a 30-31 pickup....06-02-2021, 08:48 PM -
OK as some may recall, I bought a new R and P (3.54). I'm just now getting around to assembling it. This was NOT a Mark Gear product! It was made overseas, in Italy! OK OK I know all the jokes (Fix It Again Tony) But I've seen some pretty good stuff made in Italy, too! So before returning it, I wanted to give it at least a try. Here's the problem, I was trying to set the backlash of the teeth and...06-07-2020, 01:11 PM -
I've installed the engine, u joint and buttoned things up. Question, I jacked up the rear end and spinning the rear tires there is NO movement of the speedometer drive gear. I assume that OK as the rear end is not turning the drive shaft with the wheels off the gronud. Right?06-06-2019, 11:20 AM -
I'm working on getting an A running that has been sitting since the early 90's when my grandfather passed away. I remember him talking about running a 4:11 in the rear as he had a B/W overdrive + used to tow a Mullins trailer when we would go to MAFCA meets when I was a kid. Is there an easy way to determine the gear ratio without disassembling the rear end? The car is currently not running. The engine...01-03-2022, 03:48 PM -
A friend just emailed me asking what is a good restoration book for his AA?
I think he just bought a 1928, and I can't think of any books just for the AA.
Any ideas? Thanks06-08-2017, 12:15 AM -
Did the Ford Motor Company offer any type of Waranty to the Model A/AA Ford at the time of sale from a dealer during 1928-1931?
Thanks.
