Hood latch assembly problem

[Nukes16]

Ok, here we go again. The idiot that I bought my newest project from (80 Chevy Short Fleet) replaced the original cab with an older one. The original cab had an inside hood latch release cable and the new one does not. Unfortunately, somewhere along the swap, Jimbob mixed up the hood and the rad support such that I now have a hood with a pin (which should have the external release) and my rad support has the original cable style latch release. Obviously the two don't jive and I'm not sure if I can just replace the plate on the hood so that it matches the cable latch....if that makes sense to any of you. I see that LMC offers the 2 different latches but I don't see the 2 different hood plates....just the one that I already have. If I was just to buy the external latch it appears to be rectangular but the hole in my support is kind of like a pentagon.
Does anyone have a suggestion, or swapped one of these?
Cheers in advance
