WTB : Rotary Vac Pump

[2strokesmoke]

Hey guys,
I'm getting a lil tired of rebuilding my Diaphram vac pump twice a year ( I don't think the diaphrams like the synthetic oil-or maybe they are all junk LOL )

Does anyone have a GOOD ROTARY vac pump to fit my 82 1.6D ?
Please- Only interested in a vac pump with a GOOD oil pump drive key/slot.

Need ASAP
Thanks, Mike
