Always been a torque-flite guy but now have my first glide. I'll be going through the tranny this winter to see what I actually have inside. I have had the long tail housing off and noticed it's an aftermarket housing with a bearing instead of a bushing. I saw that it still had the factory governor support with the governor removed and my first thought was replacing it with a aluminum support with a bearing and then it hit me. Is that support really necessary? Isn't there a bushing in the rear of the case? Rear case bushing and a bearing in the tail housing. Wouldn't that support the output shaft? I realize I would have to use a simple block off plate to stop pressure leakage. Wouldn't that work?

Yes the case has a bushing, I believe the only purpose for the gov. Support bushing is the load from the rear pump if it has one and the weight of the governor. They utilize the bushing/bearing for a shorty output shaft kit to support that end of the shaft. I always use the bushing thinking it limits flex in the shaft but machine the gov slip ring portion off if youíre weight conscious. Donít see why it could not be deleted though just never done it.

 Best teaching guide made. Powerglide  handbook  Carol Monroe  .Its on ebay for about 25 to 30 bucks. Best transmission part you will buy.

My thought was just using say 1/4" aluminum plate to replace the gov support and provide a good seal for the gasket against the case and let the case bushing and the tail housing support the output shaft. Yes I'm being weight conscious, I'm pretty close to the index but want to be able to run under and bring the car back to it. I've already moved some weight up front and got rid of my ballast box. Not going N&P crazy, just looking for any more that I can find. Thank you for your input.

Before you go and do that it might be a good idea to talk to one of the major builders ! I have rebuilt a lot of powerglides and have never seen a long tailshaft one without a stock support or an aftermarket one with a bushing or bearing !As Chris mentioned TSR racing products 1 800 394 5889 sells a book on powerglide racing transmissions ! They are also a good source for parts and information !Not knowing what you have as far as HP and ET you want to run makes it hard to give you any ideas on what to do ! If you are not making huge HP using a 6 cyl planetary 1.80 ratio will save you a few lbs of rotating weight over a v8 1.76 ! Another low cost weight reduction would be a lightened ring gear in your rear end ! That can save you another few lbs of rotating weight ! I hope this helps you and keep us posted on your progress !
