Some of the parts houses sell an adapter kit for those conversions. let us know your solutions as I have a B motor and transmission that would be fun to play with in my A someday.

I am not sure what you are trying to say but the B trans has the same gears as the V8.

1932 tub,
I'm going to attempt to attach pics of my B and '39 toploader and the adapters(about 4). As others said this kit..makes it a fairly easy job. Questions
...Pic #1 and 2 show pedal adaptor; Pic #3 shows aluminum adaptor(B to '39); Pic #4 shows emergency brake adaptor. Some how I lost pic #5 which is the adapter to hold front yoke BALL to bottom of trans..

Geo.,
Yup, more than one way to do the job. I just couldn't turn away from a rebuilt '39 with zepher gears that an ole time flathead racer gave me

I've got a B engine and trans in my 31 A. I've got 39-48 gears in the B box with a 39 top cover, I've got the same pedel and wishbone adapter as Hardtimes. With this setup you don't have to bye an aluminum adapter. Walt1932 tub,

How do the rear motor mounts work when you keep the B transmission? Do they look like float-a-motors and come with the kit?
Thanks,

Yes I am using a 32 box but it still has the stock gears
Thanks for that, I am out in New Zealand so don't have easy access to these parts, I will make them myself and post pics as I go.
Since you are making them yourself ... on picture #5 (of Hardtimes 2nd posting) of wishbone mount, do not forget the vertical bolt and nut just above the wishbone mount that fastens that bracket to transmission.
I realize that this picture is of the V8 kit but idea is the same.
The bolt adds an addional mounting point to that bracket to make it much stronger and prevent bending of the bracket.
I have seen several kits that did not include that hole. Must have been early versions.
BUT it is very easy to add the bolt ... if you know about it beforehand!
The bolt is helpful on both "B" and "V8" adapters.

1932 tub,
I have said that you can buy the 'kit' for what I did, but the truth is...'ufortunately' that is not what I did.
A bud loaned me his 'kit' many years ago. I looked at the adaptors and thought...geeze, I've got more time than money
, I'll just copy these adaptors. Well , if you are a fabricator and welder with equipment mabe eventually doable! However, I'm neither and although I eventually prevailed, I'd strongly recommend just buying the 'bolt on' kit.BTW..pay atn to what Benson said about the bolt ..up thru the bottom of the bell housing. I used grade 8 fine thread with lock nut/locktight. Good luck on your project..
Hmm, New Zealand...do you associate with that worthless quickchange guy..that owns half of that country
Actually that was my next question, I had noticed the extra bolt, thanks

Funnily enough I do associate with the worthless quickchange guy, he lives about 15 miles away from me. Owns half of the country.................

1932tub,
Yeah, I finally met Derek over here few months ago at a small 'charity' sway meet.
And, there on the table of stuff 'treasure' they (FAST) was selling....was my model A quickchange !! Being flaunted like a hussey...drumming up more customers !
That model a quickchange is NOW done installed in my roadsters rearend..whoohoo ! Trouble is I can't go get it, as both my hands have recently been 'warmed up' and improved...still healing. Can't give him a rating yet, until I get it running under the roadster....

Will Kimbely, I have the float a motor rear mounts on my B engine and trans in my 31 A. BUT, the bolt holes in the bell housing are about a 1/2in or so off to use the A top part of the flost kit, SO I had my own top part out of 1/4in steel, and they set right on the rubber donuts. Where there's a relitive there a will. Walt
