90 Degree speedo gear drive leaking oill

[Billw69]

Chasing an oil seep on my car and I’ve isolated it to the speedo drive unit. My car is a B1 with the stock driveline and I’m wondering, before I dive in with no knowledge if these are rebuildable? It seems as though the piece with the adjustment bolt on it is stamped into the housing?
Any help appreciated,

Thanks, Bill

Might be a better question for the bubbas over at the Boss 302 Exchange forums (https://www.boss302.com/smf/index.php) or the Mustang 428 Cobra Jet Registry (https://www.428cobrajet.org/). Their cars are more likely to be equipped with the drive reducer.

Here's a thread I found on the Boss 302 exchange: https://www.boss302.com/smf/index.php?topic=68920.msg525845#msg525845 . There are some links in there for restoration or replacement sources.

The caps are pressed in, and from what I hear, come loose on their own sometimes. I looked on Stewart Warner's website a couple of years ago, and they didn't show any parts. There have been a couple of guys on the Facebook Boss 351 group that have talked about 3D printing parts, but I haven't seen any updates in a long while.
