Hello. I was reviewing my PHS documentation and don't see an explanation for a few of the options. Thought I'd see if folks here would know or if I need to go back to PHS.

Here are the codes:
=================================================
571 - H/Restraints - upper seat belt in headliner?
241 - Adv. Assn. Col - what is this?
354 - 4 speed trans. - M20 or M21?
554 - custom trim - parchment int. anything else special here?
241 - optional loc - what is this?

Thanks in advance!!

Joe
