8m*1.25 to 10m*1.5 Shift Knob Adapter
2000 TL-P WDP 157k
TL;DR
If anybody knows of a metal adapter that works for a 8m*1.25 bolt into a 10m*1.5 shift knob, please send me link.
The Long
So I jumped on a burlwood shift knob on ebay and didn't realize it was off of a 2002 CL. In my defense, they are back-ordered at dealership for a year now and this one matches my wood inlays perfectly; how could I refrain from clicking away for 35 bucks? Anyways, my TL has a shift knob that is 8m*1.25, the knob I purchased is 10m*1.5. I could not find a metal (or otherwise) adapter that matched anywhere, so I made my own.
With the impression that 8mm=5/16in and 10mm=3/8in, I went to (Local Big Hardware) and rooted through their selection of nylon spacers. The only spacers they had available with a 3/8in external diameter were 1/2in long and had an internal diameter of 3/16in. I gripped one tightly in my vise and put my 5/16in drill bit in my cordless drill with the intention of widening the small internal diameter to 8mm. Not wanting to destroy the small nylon spacer, I slowly increased power of drill until it was effectively carving out the center and not melting or shaving away small pieces (used brand new bit). I reversed the bit out once I reached half way down the spacer and was left with a nice internal catch for a flat head screwdriver left over from the bit tip. Upon releasing the spacer, I noticed it was a little oblong. Easily correctable by applying pressure with vise in a manner perpendicular to the largest diameter of the ellipse until acceptably round. Using the internal catch left over from drill bit tip, I was able to torque and effectively thread the nylon spacer into the shift knob. Then it was just a matter of torquing the knob onto the shifter in a level position with enough force to thread the other half of the nylon spacer (now inside the shift knob) onto the shift stick. I stopped torquing the knob once I felt it was at the appropriate position with enough resistance to prevent it from moving on its own on a really hot day.
I am pleased with my solution thus far, but would prefer one that is metal.
