where to run gauge lines through firewall on foxbody
installing a mechanical water and oil gauge in A pillar pod. Also an amp gauge as well. was considering going through the grommet around the steering shaft since that's easiest to get to. Will the heat from the water and oil lines affect that grommet? any other suggetions? looked at grommet in upper left corner behind master cylinder but it's full. was thinking of going drilling holes through cowl under grill and use grommets and hose to protect the lines in and out. this is on a 1992 gt, thanks everyone.
