cab mount Question for the 3/4 ton trucks

[1962k20]

First of all Hi to everyone here. Im restoreing a 62 k-20 cab chassie with a factory pto flatbed dump body. LMC has new cabmounts for 1/2 ton but nothing for 3/4 or 1ton. are they all the same? If not Ive used hocky pucks in the past, but this truck is a keeper when im finished. This truck was born in New York and lived in Connecticut its whole life. The cab was shot so im replaceing with one from out west. This isnt my first chevy I had a 65 c-20 My dad and i shoehorned a 454 in it. Sold it when i was 18. Kicked my self ever since. This 62 is going to be looking good and i plan on useing it as a truck. But it wont see winter plowing or driving through the woods for fire wood I have a 85 Power wagon for that.
