Well, I understood you fine, better then some of the other threads I've read here. And welcome to the addiction. I assume it is a American spec VX and not a JDM. Am not surprised that a 99 Chevy part fits and worked, but many of the Isuzu Parts were sourced from the GM parts bin. Awhile back, I was trying to research Isuzu/GM part number interchangeablity but wasn't very successful. There must be away to do it though.
