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.

There are nice new ones on ebay but with their size and shape, I still have the problem with hitting my oil filter adapter. Plus they are designed for auto speedometers and do not interface with the Lycoming. Unless I can acquire the adapter that Spruce sells, I'm possibly going to need to replace the oil filter adapter with the original Lycoming that sticks the filter straight back and not like the better kind from B and S, or others.

the one from Summit has the same problem, clearance from the oil filter adapter. I'm maybe going to bite the bullet and replace the filer adapter with the original Lycoming "straight out" version.
