Are Wagon & sedan frames the same?

I have a 95 Caprice wagon, and saw a 92 Roadmaster at a junkyard the other day with a mint condition Draw Tite class III hitch under it.

I will try to post photos, but it looks like sides attach to the frame rails, then the center section bolts to the two side sections.

Id love to score it for my wagon but dont know if itd fit or not.

Thoughts?

(Sorry, doing this from a phone and the pics are oriented correctly on my phone but upside down here? Please shake your head in disgust and mutter to yourself about the newb...Im trying )

Sure. At the price you're gonna pay the yard it matters very little whether it fits. You get to confirm yourself if so, or figure what little mods it may take to work. Worst case even total misfit sell it to plenty of guys on record here who have put up WTB. Grab it!

Wagon frames are fully boxed, sedan frames are not. IIRC correctly 9C1 are?? As for dimensions and fitment, not sure and too busy now for a search, but there are differences in gas tanks and exhaust.

But a hitch in that shape is a real find.

I’d love to score it for my wagon but don’t know if it’d fit or not.

Completely agree with 96 Black.
DrawTite already profited, now you've found it.
Whether it fits your wagon or not - probably not, for reasons related to the fact that wagon fuel tanks differ from sedan fuel tanks - don't pass up the chance to learn from it, and/or sell it to us.

96 Black said it better.

Pretty much true.
The only important difference between sedan and wagon frames, is FORWARD of just behind the back door.
Wagon frames are boxed. Sedan frames should have been boxed, but were left C-channel.
Just behind the rear door is where the differences become far more significant; that is to say, I do not know how anyone could properly mount a sedan body onto a wagon frame or vice versa without important alterations to the frame and/or body becoming necessary.

The major structural difference between civilian sedans and 9C1 sedans is between the frame and the body.
a) 9C1s got ALL the body-to-frame bushings that the civilian sedans should have received.
b) 9C1 bushings were stiffer and more brittle, whereas civilian bushings were softer and squishier.

Boxing a sedan's frame, and installing the missing bushings, are both high bang-for-the-buck handling improvements.

[EDIT]
FORGOT TO MENTION: Installing a hitch onto a sedan [or wagon] is also a[n underrated, overlooked] high bang-for-the-buck handling improvement.

I wanted a hitch for my wagon to drag the mower around and found that U-Haul has a few Class II's left-

I wish that I could have found a class III before I put the class II on- not that I would ever haul anything too heavy, but just for the heavier duty build.

Valid point, however the sections and gauges, together with weldments, mounts, attachments and fasteners on the sedan Class II 'Hidden Hitch' on my FWB are identical to any Class III I have ever seen. Mine pretty much mirrors the construction in the pics above. In the past 18 years I've hauled repeat 1-1/2 ton loads in gravel, dirt, landscape blocks.....

Anything heavier I fear would take way heavier springs and elec brakes to handle safely anyway.

One more thing I've noticed is listings for Class III are often advertised as 3,500# and 350#tongue the same as ClassII. Very confusing. I just found that the case with CURT, and their application for the sedan is a generic universal RV part. Unless your mower is an 8N with BushHog then you probably feel covered with yours lol

The wagon frame is wider behind (approximately) the doors. Assuming this is a sedan hitch, its mounting points will be narrower than the corresponding points on a wagon.

It would be worth saving, however, for someone who has a sedan. Alternatively, if you're able to fabricate in steel you could modify it to work on the wagon.

From earlier threads on hitches years back I recalled the "wider" part for our wagon cousins, just not how much. Hard to think a really crafty type hasn't come up with makeup pieces considering the limited options for wagons - and that's even back when these cars were still in production.

In case this helps anybody:

91-96 B-WAGON ClassIII Part Number 41509
Can't find the part number for B-sedans [or for Cadillac Fleetwood, which may or may not be the same as for Roadmaster and Caprice sedans].
