Hi Guys - came across the following - Base plates differs on two further identical BBD's - on has LONG idle mixture screws - and the block they are screwing into is much thicker than the the other - mixture screws not interchangeable due to length

One has a 2 cast on it on has a 3... what gives? - is ther a guid somwhere with these partnumbers?

It's never junk, it's just a part you're not currently using

Just say I own a few Mopars

A "2" isn't a part number, and neither is a "3". There were variations in the throttle body casting. Some clear, sharp photos, mebbe...?

Too many people who were born on third base actually believe they've hit a triple.

I have seen a minimum of 4-5 different style of idle screws in my BBD collection.
