It was an early '90s 2500 LD, I think '92, but definatly an IFS truck. Sorry I don't know more, the truck was fairly stripped when I got my stuff.

thank you everyone
very informative
Not sure if this question has been answered, but I am trying to figure out how I can do a 14bSF 8 to 6 lug swap and keep my drum brakes:
What are the dimentions on the 6 lug 14bSF drums and the 8 lug drums? The axel in question is a 86 3/4ton 14bSF that is 8 lug. Can the newer 6 lug drums fit over the older 8 lug style drum brakes?

The 8-lug 14 bolt SF came with both 11" and 13" brakes. The 6-lug drums are 11". So yes, they will fit if you have a 11" brakes on your 8-lug. This is exactly what I did for my swap.

Anybody need any more info or is there anything else I can add to this thread?
I have a 8 lug axle from a 90 2500 Burb that I am converting to 6 lug and putting into my 98 1/2ton so its all apart if anybody wants any measurements or whatever....

Can you explain why you put spacers behind the backing plate?
For clarification, you put later model axle shafts (88 and up) into an early model housing (80/88).

Ah what the heck.
What the measurements for backing plates bolts, like the bolt circle, or the measurements up/down and side to side.
FYI, I just put a 14bsf 6 lug in my 74 a couple weeks ago.

The IFS 6 lug shafts are longer I believe so in order for everything to line up the backing plate needs to be spaced out. Also the bearing surface on the shaft doesnt line up perfectly with the axle bearing....

This is correct. The 6-lug drums also have less depth to them than the 8-lug drums. I was a little worried about the spacer setup, but I've been running it for over a year now with no issues.
As for the bearing surface issue; I shimmed the wheel bearings out so the bearing rollers ride fully on the bearing surface of the shaft.

Bolt pattern for the backing plate is the same as the 14FF as I recall, 3x3"?
One of the brake places has this info online. TSM or the like.

Ill get that measurement today...
Now I assume that I use the same backing plate for the six lug stuff since I have the 11" brakes?

Oh if its not too late, what is the brake pad width of the 11" brakes and the 13" brakes?

boy im glad this popped up or i would be out 30 buxs on a conversion ujoint, that yoke swappin from the 10b to the 14 works perfect. just had to change the dust cover and presto. also i didnt need to cut down my stock drive shaft, with a 4 inch all the way to 8 the stock shaft is good to go.
Also just put ur tape measure from the inside of the flange that bolts to the backing plate and measure 7 and 3/4 inches in and thats the center of your spring perch on a 59 inch wide from outside to outside of backing plate flange,(have no brakes on it lol)
