WTB Tach drive fitting for O-360

[teamzipper]

Desperately seeking engine right angle drive fitting for the tachometer drive out the back of an O-360 engine. This is sold by Aircraft Spruce under the part number of 10-00814, but not in stock and is on back order for 3 more months and I am grounded without it. I am converting over to an electronic tach (UMA brand) and the sender interferes with my installed oil filter adapter. This fitting I need will solve my problem without installing a new filter arrangement. I hope there is someone out there who has a used or new one available. I'm in St Louis and need it bad. NAME YOUR PRICE.

I think there are several versions on eBay.

Yes, Search EBay for speedometer cable adapter

Most speedo cables use a square tang on the end of the cable. Lycoming, oddly, needs a round one with a tab.
However... GM makes an adapter that fits over the square tang.
Texas Industrial Electric HM146 adapter. [$35 for 2] GM # 25032338 "speedometer drive key"

I used that to install this sender: https://www.summitracing.com/parts/IZL-S9013

Texas Industrial Electric has a huge number of right angle gearboxes, maybe one that'll do the job directly.
