The short filters are for the car pans. However, now when you purchase a new car pan you will get the new threaded insert meaning the old filters won't work anymore. You can swap your pan threads around from pan to pan if you want to continue traditional part number lookups.

EAO64 Amsoil or 51522 Wix or PF61 Delco is the long filter for the truck pans through 2006. Starting 2007 even on the classic Gen 3 trucks it switched to the EAO17 Amsoil, 57502 Wix or PF63/PF64 Delco for the long high capacity filter.

It's simple to think gen 3 is PF61 and Gen 4 is PF63/PF64 but there is oddities in there lol. The new Gen V engines finally spec the PF64 from the getgo..... no more stumpy oil filter. Would be pathetic if they still did.. even the 3.6 in my Impala specs the PF64 stock.

The whole 63/64 thing is a pain but is what it is too... they interchange. Amsoil used to make both an EAO17 and EAO18 but since the EAO17 covers anything the EAO18 did the 18 has been dropped.
