Help me pick a gear for my combo

Problem is, I've already dunked enough cash in the car over the years and there just isn't that kind of cash laying around for trams swaps. Not to mention the horror stories I've seen of installing newer over drive transmission, adapter plates,trams tunnel modifications,custom drive shafts...etc...etc.... If anything I would probably convert to a 4 speed stick before dealing with those headaches.

Maybe one day I will look into the "ideal" set up, but for now I'd just like a financially reasonable happy medium solution in picking a gear that won't give it a doggy bottom end but will also not be pushing the redline at 55 mph or forcing me to wear ear plugs haha
