Identifying my Current 15 Inch Wheels - and thoughts about wheel replacements

Agreed, IF the o.p. converts to 4.5 bolt pattern. I believe he is still 5 on 4. The only torque thrust style 5 on 4 I know of are team III custom order (around $500 a wheel) and Boyd's 17x7 and 17x8.
Ouch! I thought American Racing still made them in a 4” pattern…
