Read through part of the thread,

Saw the conversion chart for the B44 to B44.1, good info. My question is I just got a good deal on a BJ4 and was wondering what B44 or B44.1 parts would work on there. Not looking to do a full converion, but wanting to know what parts will work so they can be upgraded on a as needed basis. I could get a B44.1, but the deal on the BJ4 was too goo to pass on. Thanks for any help.
