getting an 8 3/4 from a 69 dart

-
Yup, I still do the occasional one. They don't come around much. The last one I did was actually the first 7.25 cone style I've ever seen.

Side gears are chipped ...junk
I guess I can sell the gear set
And build a clutch type
Or find center section
 
often thought but never tried.... and there lies the danger

machine the back off open diff side gears to make same dimension as the broken slip resistant side gear, put them and their pinion gears in and shim to get sure grip action

depends if you have a lathe and are willing to experiment

but as with a number of things i think about could all be impossible BS

obviously need to have the correct axle spline

could probably do it with the auburn style integral cone and side gear as well, take the toothy face off + some, make totally flat, put in a new gear with totally flat back and shim in between convert it to seperated cone and side gear

gear and cone ride on axle spline 1 part or 2 parts makes little difference.. if you are gonna twist that spline you will....

not worth it if you can get a clutch centre for $300 and you have no lathe and time.

but as i said earlier the cone set up is a good street and country road set up for all weathers...
if you are crossing shallow creeks and driving uncapped trails or sand swept highway, cheap and effective

if you are drag racing cheap and not very effective
although a million australians who shimmed theirs tight and went racing on a 7.8 inch diff (every car had one (mopar GM ford Nissan) (and junk yards full) and got really quite far, will disagree with me..real good quality product came out of their BorgWarner Axle plant even after BTR (british tyre and rubber) and the auditors/receivers took over..some of the centres were cast steel rather than nodular iron

the step up in australia is usually a ford 9 inch with its attendant weight and parasitic losses

enough of my rambling you are looking for a replacement... :)

the cheap units for sale on e-bay was discussed in this forum under the question '' any experience with these( inexpensive ) sure grip units '' on page 2 now ,, read post # 23 for my take on these units.
 
Think for me I'm going to re gear it
With a good clutch type
That way ill have the ratio I want
And shipping won't kill the deal
