200-4R forward clutch backing/pressure plate

[MSDGN]

The end of the forward drum shaft had snapped off. Took the trans apart and got the broken part out. Wanted to check the clutches in the forward drum and this is what I saw when I removed the snap ring. The thick backing/pressure plate is cracked, plus it has some more hairline cracks. Looks like it was ready to self-destruct. Guess it's good the shaft broke. If the plate had shattered could have been bad but since it didn't and the shaft end broke off so clean, no metal went through the trans.

Anyways I've been searching on the Internet for awhile and can't see where to get a new pressure plate, it's .250" thick.

Can someone tell me where I can get a new one.

You cannot get them new. A good used one is the best you will get. They usually break from being dropped into gear with rpm/line pressure. They are very difficult to get out of the drum at times when cracked. I should have a few though.

Bison and I have made some prototypes out of laser cut steel. They are untested as of yet and would hate to make someone a guinea pig.

Turbobitt, appreciate the offer but I'll pass. Don't want to be a guinea pig with my low mile GN.

Figures you can't get them new anymore. I'll be calling you David.

What material were these new plates cut out of? How much for one?

These were made from mild steel to see if the laser cutting could be done accurately enough to allow for the plate to fit in the drum. The thought was to make them from 4140 but the price was significant. The fit is perfect but I'm a little concerned about the possibility of cupping the plate with the mild steel. Until we try this on our own stuff I would be hesitant to give it to someone else.
The only thing that would need to be done is to have the surface near the snap ring reduced since the plate stock was slightly thicker than the factory pressure plate.
