To be honest HOskitz, I hate to say it, I would not put a lot of money into your EXT. If cleaning up the platform; checking for tweaked components, and installing bearings don't remedy what you want to hear from the driveline...sell it. My thinking is, if you do get the EXT up and running like you want, you are going to want more speed and power. The EXT is not the platform to be trying to upgrade at this point in time. Back in the day? Yeah, it had lots of options. Noadays? Mild motors is all I would recommend for the almost extinct truck
