I sold a pivot rod to a forum member and he informed me they were made wrong.
He was trying to install it on a 1976 C-160, Toro has the pivot rod part number for that tractor the same as the part number for my 1989 312-8.
The C clip grooves on his pin are appx. 5.6" apart, the C clip grooves on my 312 pin are appx. 5.8" apart.
My conclusion is there is more than one style hood pivot rod, so if you need one that has the grooves 5.8" apart I still have a few of those.
I am going to be at the machine shop tomorrow so I am going to make a few pins with the narrower grooves.
I removed the part number reference here since it appears Toro has the same part number for two different parts.
Grill pivot rod and E clips for $20 plus shipping, should be a flat rate box, so around $6
If you want them to look like chrome you can chuck them up in a hand drill and
Scotchbrite the crap out of them and they will not rust.
Not sure what other tractors they will fit, If there is a different pin for other tractors I can make those to if I have a pin or dimensions.
In the picture you can see the bottom pin is the original, it was pretty worn out.
I have 4 pins and 6 E clips left.
