I’ve got a F54Y 235 in a 49 panel

Not sure what parts are 49 and which are 54

Buying a rebuilt distributor cap rotor etc

Distributor number 1112353

I think cap in it is short

Points measure 1.25” pivot to contact

Anyway what do I order

I’m thinking the 54 up stuff

Are the distributors interchangeable pre 54 and 54 up just need to have correct caps rotors and points?

216 and 235 distributors interchangeable etc

Mostly just curious

I’m sure there’s a thread on this somewhere just didn’t find it

Thanks
