Where is the shifter? If it comes up from the side of the trans its a l43 if its from the top then its a l45.
Exactly, but its most likely a L45 as I *think* L43's were only used from 79 - June/80.
how much would you give me as a core for my 4 speed if I were to buy the 5-speed L52HD?
Just go by the core prices on our webpage. The core for a L52-HD is $250 and the core for a L43 is only $200, so you would be charged $250, and then once you sent in your L43, refunded $200, so you would be out $50-
