I had a 41 sedan delivery. It, like the 41 P/U, used the same basic frame as the 35-40 car and P/U but I'm pretty sure it is not the same as the 41 car frame.
I may be getting a little gray on top but I remember that my 41 Sedan Delivery and my 41 pickup both had a different front crossmember than the 40 Cars ...Gave more ground clearance... I did swap out the entire front end from a 40 sedan and put it under the delivery. Cadman
As long as it is a half ton it is the same....I have been going through the same only difference is the deluxe cars have the sway bar....sedan deliver, standard, pickup do not
so a 40 car axle will work who do you guys like for dropped axles I'm wanting some thing i the 2" range
Take a look at that front crossmember you can swap it out with a 40 car and that will drop the front end abou 2-2 1/2 inches....
