Not sure what salvage yard you went to, but if its LKQ, your can request certian makes and models at the desk and they’ll give you a receipt with the row they’re in.
I was at an lkq they told me to use the website since it has the row and spot, but some of the cars I was looking for were in different rows. Also the ep3 they said they had on the site and at the desk was nowhere to be found. I looked in all the domestic, all the imports and all the trucks/suv.
