10 hole question

[hwyrnr221]

On 1990 SSP i have seen 10 hole rims that have what i consider a smooth area arounf the lug pattern and i have seen some with 4 distinct indentions around the lug pattern. My question is which ones are the correct ones, and the second question is how important is having the correct ones?

Thanks, James

There were several different versions used, with different casting numbers on them. Here's a thread from 4EP discussing further:
