MF loader need help with the serial number

[Knifer]

I'm trying to find out the model of my loader just bought it a few days ago and after a day of trying to get it to fire found that the rotor button in too small for it. the distributor is number 1112457.

the tractor serial is 9a I43524 that is an I not a one

any info would be awesome thanks

The distributor number is a Delco-Remy number. On the serial number its a 1, why they used a I is anyone's guess. My 1967 135 is the same way with the serial number. If the tractor is a 135 it's a 1972 year model.
