I've read that the spring perches are welded on wider than ours in the 94 and up trucks because the frames are wider. I've never measured that tho. I do know that they are definitely wider than our axles tho.

I know that there is a WMS to WMS measurement out there, between all the disc and drum brake variants, SRW, DRW and DRW C&C...I think Nixon posted them on here a few years back...

i know that the spring perches and all that are different. i just have to move the mounts and change a couple of things. (weekend project)
i just can't remember what years are good for swapping. its either 94-01 or 94-02

the only reason i care about the later years is because they put dana 80s with rear disc brakes from 01+ on in the dodges. so if i could get all rear disc brakes with the swap that'd be great lol

yeah i would love to know the wm from first gen single wheel to second gen single wheel. i will have the axle cut down to be the exact same, so it looks normal

The 2nd gen drw pickup and cab/chassis D80's spring perches are almost exactly the same center to center as our D70's. Not sure on the srw's though since I don't have one to measure.

One significant difference is the yoke on a d80 sits almost 2" further forward than the d70. Some say you have to get 2" trimmed off the driveshaft, and some say you don't have to.. :?:

I should be starting my D80 swap in a couple weeks.

Oh yea and as ellis93 mentioned, the spring perches them selves are 3" wide vs the 1st gen which are 2.5" wide. Some people notch the corners of the perches so the u bolts fit correctly, this is what I plan to do instead of cutting the wide ones off and welding the narrower ones on.

when you say notch them to fit, do you mean you squeeze down the middle to make up that 1/2 inch difference?

Yea, they cut about 1/4" from each of the corners on the perch to make the stock I/D u-bolts fit. I seen that done in another thread, looks alot easier than replacing the perches.

IIRC, they also made a plate that matched and welded it on top of the perch.

Yea I should be starting on it hopefully within the next week or 2, that is weather and time permitting. Mine is a dually but a SRW should be prety much the same as far as I know. Yea ill try to get a few pics.

I'm betting if you put a 2nd gen SRW axle inplace of your DRW, you're going to run into tire fitment issues. DRW axles are much wider than the SRW and cab and chassis DRW variants ;)

Sorry, I was meaning the concept of notching the perches should be the same between the different 2nd gen axles. Correct, a SRW or c/c axle will have tire clearance issued with dually wheels. Thanks for clearifying that ;)

I'm installing a 1997 drw d80 in place of my 1992 drw d70 just to make clear 8)
