Nice. You wouldn't have a spare one of those and I have been looking for a prestolight book also for specs?IBS 4005 does appear in my Autolite parts catalog dated 1960
1957 D500
that is the ONLY application shown for it

I have MOPAR parts books from 1929 to 2012 car/truck
and Autolite plus other vendor books that include Mopar parts
plus superseded # Mopar part books for cross reference. About 500 pounds
of part books....a small nightmare indeed!
