Left Hand thread Taps??

I need to tap a few things and I was wondering if anyone here has Left hand thread taps or knows of a place I can buy them. I know for sure I need a 5/8 -18 LH tap, but I’ll also need a larger size, almost positive its 3/4 -16.

Any info would be great, if someone has a set that they wouldnt mind lending to me that’d be greater :). Thanks

i know here in oakville they have a place called the tool store they have them…both tap and die for around 19$ a set…its on speers rd just past 4th line
