ACDelco 20824598 GM Original Equipment Automatic Transmission Mount

okay guys I'm going to try to work through this video I'm battling the construction workers and their skid loaders trying to get enough light for the video and not get drowned out by their work effort I've been doing a lot of research on shorter than factory transmission mounts now keep in mind I'm referring to like GM products transmission mounts and there isn't really much available there are several threads through different forums where people talk about needing a shorter than factory transmission mount in order to get their proper valvetrain geometry but there's really nothing available I've researched you know I don't even know how many different threads doing Google searches trying to find someone who would at least give me a manufacturer that I could contact to try to get a shorter than factory mount most factory transmission mounts for the GM like turbo 350 400 power glide manu
