Thanks everyone!
The foot treads came from Hapco and fit very well.
I've got to take the fender pan off again.
I thought I had the creep fixed but no.......
About at my wits end trying to solve this problem.
I've replaced most all the linkage, etc. and cannot get it to hold neutral. (yes, I have the shop manual)
I've noticed that if I do get it to sit still and, for example, raise the deck it will start to creep in reverse.
Reckon what's up with that?
