Motor mount and flex plate questions

I could use some help with flex plate and motor mount questions on my Duster project.

Here is the flex plate I have. As I understand it, this flex plate is correct for my 318 and stock high stall torque converter.

I'm wondering what thread lock to to use on bolts to fasten it to the crank, also what torque specification?

I also need to find out what bolts to use to bolt the flex plate to the converter.

Wondering if and where I can get a bolt set to bolt the 904 housing to the 318...

And while I'm at it, just want to make sure these are spool type motor mounts and a suggestion as to where to get new ones..

Thanks!
