Wanted: Stewart warner tach sender. 811532

[aquariusmarine]

Hi Guys,
I,m trying to find a tach sender SW 811532 that was used to signal the older SW tachometer 811531. I have a 1970 GB36 with Lehman 120's and do not want to go though the trouble of replacing all four tachs and two senders. Also would like to keep original. I understand that these were OEM on the grand banks and Alaskans thoughtout the 70's and maybe a bit later. I have tried other senders but it seems that this sender had a unique AC signal and there is not a current replacement.
If anyone has one of these or know of one I would greatly appreciate it.

Thank You,
Yes, Chad at SW canada was very helpful in providing information trying to find a solution. Unfortunately the sender is no longer made. I contacted Brian at American diesel as well. I waiting to hear on one more lead from gauge repair expert in Vancouver as he thinks that maybe a VDO sender may work but I have to find out what the drive ratio to crankshaft ratio is at the sender take off at the starboard side of the Lehman 120 which again is a question fro Brian.
