Chris,

What made you pick the J-7402-1? AC publishes a Lorn chart at:

      http://www.aircraftspruce.com/catalog/pdf/LORDMOUNTS.pdf

It looks to me like I should maybe use the Lord J-7402-16, J-7402-24 =20
or the J-7402-37. But what about the J-7402-2, J-7402-6, J-9613-49 =20
and J-6230-1? What is the difference in all of these mounts?

And lets not forget:

There are a number of Barry mounts listed here.

How did you determine which mounts to use?

I just talked to Russ at Lancair. Here is his 2=A2 worth:

Barry
94150-01 for O-235
94150-40 for O-290, 320 & 360 constant Speed $59.00 each
94150-41 for O-290, 320 & 360 fixed pitch

Lord
J-7402-1 same as 94150-40 but cost $80 each

Back in 1998, 1,200 hundred hours ago on my plane, I switched to the =20
Lord mounts based on Don Goetz thinking that they were smoother that =20
the Barry mounts. Mine still work fine.

Now, after 10 more years of experience, Russ thinks that both are =20
about the same.
