Abfer Shift Knob Adapter Car Gear Stick Shifter Replacement Kits Accessories for Most Vehicle Truck, M8&1.25, M10&1.25, M10&1.5

The inside diameter does not have any threds.

Item is as described and work perfectly, I was having issues trying to get aftermarket shift knobs cause the shifter of my car is too small but the smaller adapter fits perfectly.

Fit perfectly

It feels like to could break these just squeezing them with 2 fingers. Not strong at all.

Fragile and hard to screw on (nothing to hold by), but work good

Worked good for me
