I'm trying to find tune up parts for my 1978 Royale. Looking through the Parts Book, it shows two different engine assemblies for 1978. One of them, 561032, reads, ENGINE ASSY - type 403 CID V-8 gas code RA (STD) (eff w/ 1978). The other, 561033, reads, "ENGINE ASSY - type 403 CID V-8 gas (RPO NB4) (eff w/ 1978)

How do I know if I have a standard or RPO engine? Its not listed on the VIN tag as an option so should I assume that its the 561032 assembly? I ask as they have different distributor caps...
