Yes mate. Good question. Just mocking it up at the moment. I estimate halfshafts to be around. 250mm ( 10" ) give or take. I got a price from action driveshafts. $300each for halfshafts 4" aluminum .125 wall. Driveshaft the same.. debating 1350/1410 uni's . Outer stubs 40spline 200mm long with billet 1350 yokes.bolted..
Inner stubs. 35spline. Billet yoke bolted. Not sure on length. Not up to that stage. But will comfirm at a later date..
just centralizing everything. No hickups yet🙏

Wow looks like a decent set-up, I'm not much of a powerglide fan for a street car.
Rob, you going to use an iron ford 9in? Not sure if you have seen the dutchman aluminum ford 9in housing. They have an option of using cv or spline stubs. I think you could build a batwing pretty easy for the rear axle.

What a sweet car, keep us posted on your development.

Dang that is a beast! I love to see people building up super beefy C4s... nice job.
This probably isn't an issue, probably... but I noticed the tire on the right front wheel is mounted reverse tread direction. I guess those aftermarket wheels can be rotated positions?

Yes mate. Steel housing. Only bcos i can weld brackets to it to connect up the c channel. Just mocking things up at the moment. Making sure everything connects together. Yeah. So far so good. Dont jinx me👍

Yes Joe. Its pretty basic. Well keep in mind. What we are doing is the drive train only.. nothing wrong with the suspension irs itself. So why touch it. Alot of people are doing half shafts/spindles but eventually there centre will say enough enough pls.😊 amazingly. This housing lines up perfectly within the tunnel. All fun mate

….. I posted the video because of the 9" IRS diff that he is pointing at (around the 4:00 mark) … not because of the Powerglide … Someone is making compact 9" IRS housings …..

What do you plan to do about the axles?
This is my main concern when swapping over to an IRS 8.8.
C-beam adapter and batwing aren't an issue. Its the fact that the axles act as the upper control arms.
Finding an inner axle stub that will work and accept a 1350 or 1410 U-joint is becoming a struggle.
And what about the hubs? Do you plan to upgrade the hubs to accept larger spline outer axle stubs?

40spline outer axles getting made as we speak. Custom machined hubs with 45mm bearing to accomodate the axle.... 8" long with bored out 35spline yokes resplined to 40. The inners will be 43spline only bcos u can buy billet 43spline yokes
But into the diff it'l reduce to 35spline .As u cannot run a 40spline full spool centre on the street. Will post pics of the axles on arrival. Cheers

I considered C7 wheel hubs with forged outer stubs (they are cheap and widely available for offroad stuff) Getting 1410 U-joins and 3.5" chromoly axle shafts is easy. My issue then becomes the inner axle stubs.
Doing it affordable is the biggest hurdle. I guess I could find decent shelf-parts stocked somewhere and have the inner stub machined for the stock style D36/D44 snap ring for axle retention.

Are you saying that the C7 wheel hub ( 33 spline 1.410 diameter ) will bolt on the C4 spindle? And there are stub axles available that fit with 1350 or 1410 u-joint?
