Hurst Competition Plus 4 Speed ID # 990342M. Just picked this shifter up and would appreciate any help on its application. I have searched the number from the main body but to no avail. There are numbers on the three bottom levers. one is 7265, 7267,7268. There is a number on the bottom of the chrome shifter lever 7275. There is also another number on the main case 3138. Thank you.
