You probably won't have much luck on here since this site is pretty much dedicated to the 6G Galant using the 4G63 engine. I am however confused since you said you have a 1992 car. Is this a 6G car with a 6a12tt swap?
If not and you have a different car, you might want to try one of the other Galant forums for help. Try sending a PM to 4Grim on this site as I know he has an 8G Galant and is active on some other sites.
Would help immensely though if you could post up a picture of your car so that we know what we are dealing with. If it is a 6G car we may well be able to help.
