L275 (and others) tach drive assembly needed

[LeadHead]

I need a tachometer drive assembly/housing (or whatever it's called) that bolts to the front of my L275's engine. It's where the tach cable connects. I know there are several different models that have compatible parts including (I think) the L235, L245 etc....
Anyone have a used one they'd part with for a fee?

These are known compatible models, and there are probably more of which I am unaware.
L235, L275, L2850, L2050, L2250, L2350, L2550, L3250, L3410, L3750, L4150, L4200, B1550, B2150.

L185DT same as well?

It looks VERY similar but has a different part number than the other models listed above.
