37-41 Axle

Attached is a picture of my 37-41 front end axle and perch bolt.
The perch bolt has two eyes (Bosses) the lower eye is a little wider than the top one. Not sure what this is for. This is different than the 41 deluxe sway bar stabilizer perch bolt set up where a swivel is attached.
Also notice the large bolt going through the axle which could be for a shock absorber.
I'm trying to figure how I will set up this front end up for the proper steering and shock absorber parts.
The spindles are 1937-41. I will be installing new king pins and hydraulic brakes and running 35 wire wheels under a 35 coupe 5 window.
Hope the picture is attached. IMG_0566.jpg
 
The axle is setup for tube shocks, if you are wanting to use lever arm shocks it will require some mild modifications. Need to remove the shock bolts (mainly for appearance) and determine how you want to connect the shock arm lower link. If you are using the radious rod shock mount you could use a 37-39 bolt, or leave it like it is if you don't mind the look.

To me it looks like a perch for mechanical brake linkage, bottom & the top boss would be for the lever shock link.

Second look says it's a '48 axle with a tube shock mount on the back & the perch pin looks to be from a mechanical brake setup. incorporating a shock link boss on top.

The perch bolt is for 1940 early stabilizer. A rare stabilizer with many parts. upper hole for a shock link and lower for the stabilizer swivel. It can be replaced by the 40 later style perch bolt which will make it much easier to find a stabilizer (late style).
 
Maybe another option for you to consider, if you are not going with a stabilizer bar, would be to use a set of axle bolts like these. These were removed from a '37 coupe and carry a 78-×××× pn, but were probably used up to at least '39.

I learned something today.
 
Thanks for the comments. I kind of do think its a 1940 perch bolt set up for the early stabilizer which isn't seen or talked about much. I would prefer not to change the perch bolts. I have a lot to think about and learn before I can proceed with the axle maintenance and future set up.
 
TerryOH is correct once again. Man, that guy is smart! The early design sway bar in 1940 is very rare these days. I had installed one just this year upon a coupe I had restored.
 
I'm learning something here too. I've noticed that one of my '40s has a sway bar and the others don't. You mentioned that they are rare but was it an option? Is it factory? Thanks,
Richard Grace

Richard, A sway bar was installed upon ALL deluxe models. It was available on the Ford V8 models as an extra cost item. There were two basic designs. The first design was troublesome from the very beginning and underwent a few changes of its own during production. The appearance of the entire assembly was upon a quick inspection only slightly modified. The second and final design was the one that worked well and was much simpler in design than the first.
Only the early design is rare (these days) as they were replaced when a 40 was serviced at a dealership. Subsequently the "old" parts were to be returned to Ford for a credit and then destroyed.
Obviously some escaped this demise and can, albeit rarely, be found.
Service parts for the early type are also nearly impossible to find. Why? They too were to be returned to Ford for credit and likewise, subsequently destroyed.
 
The only Ford axle bored for the tube shock was the 48, However, Someone may have bored yours out. only way to check is to measure the length 42-48 axles were 2" wider, I think.
