It is a very easy swap...
The Pro 5.0 will come with easy to read instructions, basically consisting of:
Take off shift bezel, unbolt the 4 rubber boot bolts, unbolt (1/2"?) the 4 tranny bolts, and use the shifter and pry up on it. It will break loose with lots of silicone around the tranny/shifter. Clean it off with a razor blade, scraping away from the transmission insides. Apply new bead of silicone and the install is pretty much the reverse steps. You will have to trim the rubber boot, and the instructions come with a template. Then adjust the stop bolts (so you don't overshift and bend/break a shift fork). You can adjust them in 3rd and 4th gear. You put the car in gear and back the stop bolts one turn from the 3rd and 4th gear.
Again, the Pro 5.0 will come with great instructions and it is easy...and it comes with new longer bolts I believe, so you can shift harder
I have not tried the
BBK shifter, but I have had two Pro 5.0 (just installed one on the '98 last week), and a Tri-Ax. Tried
Hurst and B&M.
My preference is the Pro 5.0 (shortest throw of all shifters), with the Tri-Ax right behind it.
The Pro 5.0 feels very stoute and built tough.
