My apologies for the delay, Doug, it’s been busy lately and I still have to scan the documents so I can email them to you.

I’ll scan the data pack and email it to you, Doug.  You use the 65 engine mount and use a 65 accessory case on the 90: no electrical will fit ahead of the firewall, just the two mags.  With a Marvel MA-2 carb, you have mixture control, so you can lean & cruise about 95 at 2050 rpm, burning 3 gph (Stromberg equipped engines can’t do thar.  To get enough carb heat, you run cold air thru one heat muff, run that heated air thru the other heat muff, then into the carb airbox.  Prop is a 72-49, like a Stinson 10A uses.

Welcome to our wee club for the skinny birds, Doug!  You’ll find lots of useful, and some useless, information in the forum, blog, and photo sections to help you with your restorations.  Good luck staying retired while you maintain your IA!
