F3000 Acronyms

A lot of F3000 teams in the past have used acronyms instead of using their full names.

Can anyone tell me what the following stand for?

AC&E
AGS (Automobiles Gonfaronaise Sportive?)
CDM
DAMS
DKS RACING
GA MOTORSPORT
GDBA
GEM (Gary Evans Motorsport?)
GJ MOTORSPORT
GP RACING
GS SRL
HORAG/FTL (FTL=Formula Team Ltd?)
ITI 3000
ORECA
PMC
PTM 3000
RAM
RCR
RSM MARK
TOM'S
TWR (Tom Walkinshaw Racing?)

I have guessed a couple already but it would be useful if they could be confirmed.

Thanks in advance.
