8.8 diff cover

Okay guys and gals. I hope I’m not learning an expensive lesson. I swapped in an 8.8 into my 83 fox. I decided to reward myself with a pretty b&m diff cover. I liked the fact that it had drain and fill plugs. Problem is clearance between the spare tire well. Is this typical with these types of diff covers ? Do you run into this with the ford racing cover ? I really don’t want to massage my spare tire well with a hammer.
