Tristar sent me a relacement bushing for my P-100 (same bushing as the T-100). You need to align the roll pin bushing slot to the slide hole as close as possible. If you don't do that, you'll never get the new roll pin in all the way. I aligned the new bushing and just banged the bushing in by grasping the slide and hitting it against a 2x4. I wound up sending my slide back to Tristar for them to finish installing the new bushing because I couldn't get the new roll pin in all the way. If I had to do it again, I would have done the same installation, but this time I would run a proper sized drill bit through the frame and newly installed bushing before attempting to install the new roll pin.
You can send in your slide, barrel and recoil spring to Tristar via USPS for $5 since the slide is not considered a firearm.
