[WILMASBOYL78]

Sully is correct...what tranny do you have in the car..?? 3.55 axle ratio was the norm for the L78 cars, but there were other choices. If you have a 4 spd you may want to consider some options....M20 works well with 3.55, M21 is a little doggy off the line with that ratio. Most "run of the mill" 4 spd L78's will have the M20/3.55 combo....you can't go wrong with that choice. How you plan to use the car is also worth considering...street, track, show car. Maybe you can fill us in on some more details and how about some pictures...wilma
