Default 3995647AP Pulley Application

I tried using the search on this site but haven't really been able to nail down if this was an actual asembly line installed part or a servie replcement piece. If this was actually used on the assembly line, what year and application was it used on?
Thanks
Matt

I "think" that is a service replacement part for the 70 6060AP W/P pulley that was on all BB 70 solid lifter assembly line, could be wrong though

Matt, 71 Chevrolet parts books list this pulley for the 71 LS6 Chevelle engine, of which no known documented cars have surfaced? I always wondered if any 71 Z28's might have used these as I know that 70 Z's have been known to have either the 69 824 pulley or the 6060. Maybe some 71 Z owners can enlighten us on this. Otherwise my guess is it ended up a service piece replacing the 824 and 6060.

What is the typical factory installed WP pulley on the 1970 L78?

popular opinion is the 824 on early 70 L78's and the 6060 after the LS6 came out
