Filter numbers

[Engine5]

Ok, I did the search here and unless I did it wrong I can not find a definitive number for an air filter. The truck is a 1969 M51 w/ continental multi fuel. The fuel and air filters are clogged up real bad. I need to replace them but I am having a hard time finding numbers. Most of the threads I looked at are not definitive. I need to give the numbers to the town mechanic who doesnt know squat about these engines or any others for that matter so I need him to get the right ones the first time. I am willing to take any help on this one. Thanks.

All the following are Baldwin filter numbers

Oil P20HD( the gaskets are correct for the canister base on these)

Secondary Fuel PF 902(the canister gaskets with these are not correct)

Secondary Fuel filter canister seals G241

I don't think there is a direct crossover for the primary fuel filter on a Deuce or a 5 ton multifuel,I order mine from Memphis Equipment Co

I've got a pair of P20HD filters for my deuce. I see the large gasket that came with them. But the smaller ring...is that the gasket for the center post on the housing body?
