I’ve done a few diffs in the past and my go to perches are the mopar ones they’re the same as these but about $12 at the local Chrysler/ dodge dealer parts counter or at summit in case you do this again
The main thing i see that I'd do different is when welding the tube back together i would have run those beads up instead of downhill , you get much better penetration welding up and that means a much stronger weld , other than that thankyou for the video , very informative, i have one of these axles im shortening this weekend for a good friend of mine
Nicely done! What lower spring plates are those? Shock location is same as my 10bolt I’m removing from my nova. I’m doing same swap for rear on my 69 nova currently. Narrowing it. No mini tubs what b/s are u running now with it narrowed on wheels. Thnx
I believe they’re the original plates I just modified them for the shock relocation. For now I’m using wheel spacers but I’ll make sure to post correct backspacing when I order new wheels
So was watching your video and i was writing down measurements on my end if axle is 20 1/4 “ and if you cut out 2 7/8” i come up with 17 3/8” just wondering how you came up with 17 5/16 ? Just making sure before i cut mine could it be thickness of cut off wheel ? And also did it center under drive shaft tunnel great video by the way 😎👍🏻
Honestly you’re probably closer right on the measurement. I used a cheap tape measure and probably didn’t account for the width of the cut off wheel. Drive shaft is dead center and so far no issues 😎. Good luck on your project!
Hi so i did the mod and shortened the one side how u did so im in the process of mock up rear end to weld brackets on the axle tubes but my question is when i try n center it the pinion still looks like it is more to one side than the other im trying to put this in a 63 chevy impala so its the x frame when i look down tunnel it looks more over to passenger side still its not alot but its noticeable so does the pinion and driveline have to be super centered of is there some forgiveness here? Not sure if this set up will work on this car jualst wanted to try it
@@alfredopolojr6212 i don’t think the drive shaft ends up perfectly center but it’s much closer. The reason for the 2 7/8” cut is so you can use factory axle shafts. If you need yours closer to center you’ll have to figure out another solution for shafts. Hope this helps
@@dumpsterfiregarage im just curious how far u can be over before any vibrations will occur its not over alot but u can see it i did do the 2 7/8 and used another shorter axle everything bolted back together fine ive never seen it done to a impala but i wanted to give it a shot everybody usually does the 9” in these i wish i could show you pics see what you think but thanks for replying
This is not the proper way to do this. The goal is not just to narrow the housing but also to get rid of the c-clips and, in the process, install larger outboard bearings with positive axle retention. Cut off the housing ends and replace them.
A hose clamp makes a good cheap guide for cutting square instead of tape.
Great video, been wanting to get an 8.8 for my 57 Chevy wagon but completely lost on how to center it. Thank you for the encouragement
Nice! I just did the same exact repair on my channel for my 55’ Chevy Truck. They’re good solid rear assemblies!

That’s some good advice. I don’t pretend to be a very good welder, i just hope i don’t have any issues with this axle in the future. Thank you!
What a handsome boy!

Might need some shop space when it’s time to paint!
Why are you using adapters? To keep Chevy wheel? Nice job on this also.
For now they’re just to correct the backspacing with the narrower rear axle. I drilled the axle shafts for the Chevy wheel pattern.

@@alfredopolojr6212 as long the drive shaft isn’t going to hit anything, i think you’ll be ok
What back spacing are you running with the narrowed rear end? Doing same swap on my 70 nova. Currently running 275/60/15 on 15x8 rims with 5.5 bs.
Fins Up!
Subscribed!😁
Are you using the 4.5 lug pattern?
5x4.75. I just drill the shafts and brake rotors for the Chevy bolt pattern and pressed in new studs
Nice tutorial! Wear gloves when welding you slacker! 😂
Always!

C clip eliminators would be ideal but this will work just fine for my purposes. Thanks for watching!
