Customs 1939 drop axle

I’m looking to put a drop axle on my deluxe. My wishbone to wishbone measurement is 38 1/2. I can get an axle that’s dropped but the wishbone measurement is 40. Would I be able to run that or do I need to find one? that’s 38 1/2.

 

Do a little more research. Check with Jason at P&J's/

 

Or have the original stretched

 

I’ve got a 42 that I grabbed a dropped 37-41 axle for. Basically opposite scenerio from you. I wanted the narrower width to tuck the wheels. I’m narrowing the perch center of the later wishbone and going to run a narrower 40 type spring. . You can make anything work but your spring will end up being the wrong width.
The short answer is with the right combo of parts and modifying your wishbone it could work maybe but I wouldn’t want that wider perch configuration under a 39 personally and it certainly won’t bolt together with your spring and wishbone

 

Thanks will do.

 

That was original plan. I just have a buddy that got one that’s drilled and chromed laying around seeing if it would’ve worked.

 

Appreciate the response I think I’ll just go with stretching what I got was hoping the one my buddy had laying around would work it’s drilled and chrome

 

IF you are not wanting to split the wishbone
this video shows you the 48 wide 'to king pin' axle with 35/6 bone 36.5 perch
and a dropped axle with the 37 38 39 40 38.5'' perch distance unsplit bone
same spring on both
note the abruptness of the drop of the larger perch distance over the nice swoop of the narrower perch
if you have a 42-46 axle with the 40'' perch centres
the spring would need to be wider

note
on pickups and maybe cars
what you cannot see is
in 38 the fenders get wider by 2 inches per side
the running boards are wider too
even though they are the same ch***is

 

I have a Magnum Axle 40 dropped axle in my avatar. That axle is now made by Super
Bell. They work great and are virtually a bolt in. You will have to cut the original steering arms off and use the deep drop bolt on ones though.

 

Exactly; we used that axle on a '40 and other than dealing with the steering arms it was a bolt-in deal. Also used a Posies reversed eye spring. Car sat real nice.

 

Rebuilding my avatar, I had a N.O.S. 37 tube axle & a new 32 reversed eye spring I used with the Speedway adjustable perches that permitted using the narrow above axle mount & the 32- wishbone flexed enough to mate to the axle bosses, in the final ***embly I desired more clearance around the flathead rear engine area so opted to use the longer stepped & unsplit 42-48 wishbones by repositioning the rear ball mount, the unused forward 42-48 type spring mounts were retained & serve as shock mounts.

that what a stock axle dropped looks like
or for the 300 and something dorrars
you already have a stock reversed eye spring
and yoou get some what should be nice condition spindles with the arms already dropped
and the axle is done too
or, even betterer - -you can simply wang that whole lot in
see if you like it
n.b. buy a new rubber ball and split pins for the pivot.

 

I think mine sits right with just a Posies rear spring and Posies reversed eye front spring. Ron

 

Did you run into any problems with the front spring setup?
Shocks bottoming out or hitting bump stops?
I'm debating between dropped axle or Posie 2" reversed eye spring.

 

No problems at all. Second time I used the same approach. Ron

 

Thank you, Posie spring it is.

 

it not a drop axel it's a dropped axel..... learned that to day...

 

Actually it's a dropped axle. Ron
