I can reason out and mathematically prove how a GV is an advantage. In the real world, I have zero experience, in my head, I think about it all and I can not find a single reason to purchase or use one. IMO, it is not cost effective. My wallet is to thin to play with one. I myself would rather use a factory 4spd auto or a manual trans that has a OD gear, be it a A-833 or Tremac variant.
BUT! This is just me.
Did YOU make a big MISTAKE?
IMO, I don’t think so since you thought about it and decided to make the leap. Your reasoning was sound in your head, go for it. And enjoy it! I called out to AJ/FormS because he has one and loves it.
AJ is a good man and a solid dude that will help you out.
He gets my stamp of approval and a big thumbs up.
