Any experience with Rennline short shift kits or any other short shift products? Thanks in advance.

I like mine and it's on a '74.

It has two set-ups IIRC 60% and 40% of the stock throw. I'd start with the 60% and get the feel for that first.
You still can't speed shift it into the gears, that's more the 901 (914) tranny issue than the shifter, so you have to slow down your shifting a little bit. Also I have trouble shifting into 1st from a dead stop, I learned to take my foot off the brake while shifting into 1st.
My 914 is a 3.0/6 conversion, so I only have to use first as a granny gear if I'm stopped on a grade.

I wish the reverse lock out (option, included) had a knob trigger, because with the lock out you have to use two hands to shift into reverse. That said I didn't add the lockout option and I've never hit reverse.

Over all I like the Rennshift, way better shifting and I like that the knob sits further back than stock, but mainly because of the tranny it's not perfect.
