I guess I'll pass on this purchase, since it's been 3 weeks with no response :
, and I no longer need it either.
While waiting, I got bored and put together a parts list to accomplish the same function.
This is what I ended up with after a few minutes on ebay...
1 oil galley plug (already tapped for 1/8npt) - $25.00
1 chrome 90* elbow - $9.50
and 1 Marshall liquid filled oil pressure gauge (same one used by Joker) - $18.00
All total, with shipping, was just under $60.00
So... Thanks for not responding. You actually saved me money
