NP205 to adapter Mounting - Bolt size?

[YukonFerrari]

Hi All. I've done some searching but came up blank. I'm putting in a 400/205 to replace my 350/208 but need to determine the size of the bolts to use for mounting the 205 to the adapter (have 205 and adapter but no bolts). Would anyone happen to know the size/length of bolts to use?

I was also contemplating if studs installed in the mounting face of the 205 would be the way to go for easier installs/removal. If anyone's done this, what would be the size of studs to use?

Thanks for the help.

I'm rebuilding a figure 8 NP205 right now. I see if could get the lengths tonight. It should be 3/8 coarse thread.

For figure 8 NP205 to adapter, 1x3/8-16.
Adapter to TH400, 1 1/2x3/8-16.
