MM D50 Noob... Jus bought a D and want some wide wheels

Finally found this site and jus bought a D50. Looking for some 14x9s or 15x9 or 10s to fill the gap. Is my wheel bolt pattern 6 on 5.5"? What other vehicles cross over for wheel bolt patterns and hub bores? I think my B2000 wheels will fit...

thanks dewds...

Any mazda, nissan, and older isuzu truck wheels will fit. Also 4x4 toyota wheels will fit. Any 6 lug full size chevy, cadillac, wheels will fit if you bore the center hole out. It is a 6x 5.5 bolt pattern. You will have more luck on getting a 16" aftermarket wheel than going through the hassle of boring a GM wheel. Most aftermarket wheels have the bigger center bore already.
