T-6 has a R-1340 and this appears to be that type. They will also fit a R-985.
There is a standard size and a oversize.

That mag couplin is used on the Pratt and Whitney R-985 and 1340 for the Bosch and Bendix magneto.

The 1/32 embossed into the side means it is oversized by 1/32 of an inch to make sure there is no gap, or slop, between the engine and the mag due to wear.

If you're giving them away, I would take them (of course I would pay postage). My engine is zero-timed so I might not actually need them for some time however. Of course if I had them on the shelf I would likely never need them! :wink:

There are actually THREE sizes, standard; =1/32 and-1/32 (I think those are the sizes, don't shoot me if they're 1/16th).

If your newly o/h'd mags won't bolt in, the "hockey puck" is too thick. Ask me how I know this!!

Anyone running a 1340 or 985 ought to have one of each. They are relatively cheap from Covington or Savage Magneto, but shipping and the wait time is also a bear.
