repairing a cut shift knob...

[jakc993]

hi guys

new to the forum, again trying to change the knob too. purchased a momo combat evo air metal knob for the box but it doesn't fit. man what a dissapointment. well i am going to sand down the inside of the momo knob and try to make slightly larger to fit. and since this will probably be cheaper to replace the knob than anything else. i beleive its off just by a little, haven't actually measured the exact measurements but hope this works. then i will use a glue gun and hopefully this will place it in position. anyhow any help will be appreciated.

It's like they say, you can't fit a square peg into a round hole. So unless you do some sanding of the shift knob or cutting the inside of the knob to make the round hole fit around the square shaft of the shift rod, your not really going to ever get a nice tight fit. You could try hammering that sucker on after you do some sanding or cutting, but it will be a ******************** to get off later on if you ever needed to. And if you hammer it down you will never get it all the way down the shaft, creating a much taller height in the shifting throw than the stock knob, unless you cut the height of the shaft too. Kinda sucks either way. I would just buy a nice Porsche made shift knob on e-bay. They always have them on there real cheap.

I have a MOMO air race knob on my Boxster. You need to be patient and careful in shaping the stem otherwise the allen head securing pegs will not be effective and you will end up with the same loose feeling you reported earlier. Good luck, the metal used in that shifter is tenaciously strong.
