I need new front rotors for my 76 f250 highboy. the ones they show here have 2 different ones. before serial #y20001 and after serial #y20001.. what is that serial number, and where do i find it?? is it in the vin or..??
thank you..

the serial number is in the vin number located on face plate on driver side door or in the glove box. look for the last six digits, that should tell you your serial number.

the last 8 digits are YLB93*** though..

4. Remaining six characters - 100001 - This is a numeric code for the vehicle build sequence. In some cases there could be two letters and four numbers.

looks like your serial number is after 20001 (i'm not sure about the letter or it makes a difference with the numbers because i think it can get confusing) can you look at both rotors and see what the difference is and compare to yours?

[76HighBoy]

well i was just looking to order them online, so i dont have them in person. i called jbg but they dont know the difference lol..
