bought a chrome inner primary off of ebay that is supposed to fit my 99flht.Seller stated it came off of a 2000 road king .Well i pulled mine this evening to put it on and there are some minor differences .The one that i just pulled off my bike has a 94 as the last number in a group and a 99 cast date .The one i bought has a 2001 cast in the back .They look similer,but are some different .It looks like just different internal bracing and a different way to feed/drain oil to jackshaft bushing.I just don't want to get it almost on then figure out why it won't work.Any input greatly appreciated .I have put off the install until morning in the hopes i will know more by then .I'm assuming mine being a 99 there is some carryover evo stuff still used on it .I just don't know what will interchange .sorry to ramble .thank you
