Personally I would reuse it. Normally I would spin it in a lathe to clean it up or you could use a sanding disk to clean it up. This being the forward clutch its not going to hurt anything. Remember this clutch is normally applied in all forward ranges and as long as its flat I say run it.

 

Thanks Vince, I finally figured out that they are talking about spline length from top to bottom. I have a few other end plates that look like this but aren't warped or anything that I had planned on replacing. Ive run my fingers over them and cant feel any of the hot spots so I'll just go ahead and run them

 

Wanted to bump this thread back up to say thanks to Vince and everyone else who helped out. Got the trans completely back together and looking to install it shortly. Have a couple questions (hopefully the last ones) about the yoke/output shaft/etc.

I have the output shaft with the bolt in yoke pictured below


In the pic I do not have the O-ring on the output shaft, is this needed? Since the new slip yoke I have does not have a vent hole in it, the yoke becomes pressurized when I push it on to the output shaft. I'm assuming since the fluid has no way out, I can leave this O-ring off?

The slip yoke is a long th400 yoke with the 2" counterbore and 3r Ujoint. As you can see below, the yoke bottoms out on the shaft before the shaft bottoms out inside the yoke.




If I measured right, there is about 3" of spline engagement inside the yoke. Since it seems like I might need to shorten the driveshaft, would it be better to shorten the yoke a bit so the output shaft goes deeper into the yoke? If I dont need to shorten the shaft and there is 1/2" to 1" of play, is 2" or so of spline engagement sufficient?

Dont mean to be long winded but i'm on the last leg of the race here and dont want to be sitting around with the truck down for weeks because I missed this.

 

Anyone?
