I picked up a Holley carb off a 1983 fire truck with a 429 LIMA 4V to convert my LN800 dump truck with the same motor from propane back to fuel. The numbers on the carb are listed below. I was looking for a carb kit for it and now am wondering if it is obsolete as I can't find any by googling the LIST number. Can anyone enlighten me. Thanks in advance.

E3HE-9510-DA
LIST-9917-1
0063
