i dont know about the razo one, i got one similar to it from autotechnica (ordered thru summit racing) that presses down, ive had a couple of small problems with it

1. collar was too small to fit over shaft... so i bored it out
2. had a round collar meeting up to square cover over shaft.... so i removed the square cover
3. had a round hole coming out of the square cover's slot, looked awkard (and shaft was unfinished).. so i put a shift boot over the shifter

i think this one was specific to my VX/install

the shiftlock release wouldnt come up all the way sometimes, so i had to rig up a spring in there to pull the release out all the way

im in philly so if you did order and run into problems, i could probably meet up with u and help you out
