Not exactly sure when Toyota did it but they didn't make the tailgate handle in chrome fer the SR5 package fer the newer T-100 models...I'm guessing 1995-98. Go figure. 
Luckily...I had a spare tailgate from a 1994 T-100 SR5 with the chrome handle. It was in good condition...not mint but didn't matter to me.
So a quick turn of the screw driver, popped the latching off, and I have the chrome one out. Luckily the bolts that held the handle to the gate were 10mm bolts so that was easy taking them off with a nut driver.
Unfortunately...on the 1998 T-100...they use #2 phillips head bolts instead. They stripped out almost immediately...so I had to break out the drill and drill bits. It's off in a few minutes with some cursing under my breath.
So now all my handles around the 1998 T-100 match up in chrome.
