I can't see that it would be much harder than my BX. I remember a post (and also a local dealer telling me) that the 60"MMM with the 302 loader has some clearance problems. I don't know if this has any thing to do with the extra effort needed to remove the MMM or if it is even true. I was told that a 272 FEL was to be ordered if you wanted a MMM. If I had gone for the 7500 I would have ordered it just as you have.
BTW, who was the dealer? I see in your bio that you are in South Jersey. I'm in NY (Long Island) and I went where you are to Advantage Sales to get my BX. Great service, prices, etc.. If you bought it there (or even if you didn't) those guys will be happy to give you any info/help with your problem. Ask for Bruce.
