Technical Overdrive Bolt Info

I put a 1951 Ford Three Speed OD transmission in my '49 Ford Coupe.
The solenoid for the OD was missing, so I bought one for it.
A friend put the transmission in the car, and I am somewhat handicapped, so unable to crawl under the car to see what bolts it requires to install I am asking of anyone can help me out.
Thanks in advance.
Cheers...

 

The solenoid is held on by two 5/16/- 18 bolts that are about a half inch long

 

Appreciate much !!!

 

Is the solenoid installed and engaged yet, or is that yet to be done?

 

About 18:16 into the video you see how the solenoid goes in to the transmission lined up with the flat side to the slot and then turned about 1/4 turn to line up the mounting bolts and the pawl.
