I was cleaning the grime off of my transmission (SM420) and changed the fluid in it (SAE90W Mineral oil) and noticed this decayed chunk of rubber sitting on top of the transmission. It sat sandwiched between the cab floor, (or access plate for the transmission) and transmission itself. Looks like it may be important out here in the desert to keep dirt and dust from wearing down the shifter where it meets the trans, A huge chunk is missing and it looks to have been for a long time now I was wondering if it looks like the sand got to it already (pic 3) I have looked around online, Googe and LMC and classic industries, but cannot seem to find it anywhere. I was thinking if somebody knew what it was called that would help me search for it. (pic 1&2) Thank you in advance.

Grab a sharp knife and a piece of foam rubber thick enough to squeeze tightly between the top of the transmission and the floor pan, and you can whittle out half a dozen of them in a few minutes. It's not likely anybody is going to call you out for not having exactly the right shaped part in a place that can't be seen! Jerry

The best tool I have found for cutting foam rubber is an electric knife. They slice thru foam like butter. Don’t run out to Wally World and spend $$$, as you can buy them at yard sales for 3 dollars most anywhere.

I have always used a hot guitar string (G), take 2 wooden dowels drill a very small hole through them run the string in one side then tie it to the other with some needle nose pliers, heat the G string with a propane torch (be careful not to get it to hot). you can cut any shape you need just don't burn yourself or anything you love.
