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?

Seems like a major conversion just to keep the leave spring?

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?
