Checking bolt pattern

Hey I'm selling some old rims of mine and someone asked me the bolt pattern. I know they are 5 lug but is there only one pattern that fits our cars? I'm guessing its 5x4.75. Is there anyway to check for this? I have the part number and contacted the manufacturer but they haven't gotten back to me yet. When I look the part number up online, I can't find anything. They are American Racing rims, 15x7 part number AR-235612MS. Thanks.

5x4.75 was the only bolt pattern ever used.

All the part number will say is what rim it is. The rim is/was probably available in many different bolt patterns.

The 5x4.75 bolt pattern is standard Chev small pattern. The large Chev is 5x5. It was used on 1/2 ton trucks and A,B,G body cars with a heavy duty option. Ford cars use 5x4.5

Here's now to find the pattern size
