Banjo bolt torque question.

Five Questions: I'd like to know:

1. What amount of torque (ft. lbs) or(inch/lbs) is used to tighten the bolts that secure the torque tube flange to the banjo rear of a 40 Ford like the bolts in this photo. Or, is it one of those cases where you do it by "feel" ? It feels like these bolts have a tighter class of fit.

2. Is it best if those bolts go back into the same threaded holes they came out of?

3. Is it ok to use fishing leader wire to safety wire those same bolts?

4. Can I use Blue Loctite with or without the safety wire ?

5. Is better to separately safety wire two bolts at a time (see first video) or use one wire for all the bolts?

Second video: http://www.jalopyjournal.com/forum/threads/tech-how-to-safety-wire.215935/ The last two photos show what I think is the OEM style wiring as I bought the car in 1963 and have never messed with it. Is that really the way Henry did it?
I noticed it was the same on the 41 rear of a friends car.

Thank you.

1. 35 ft. lbs should be heaps
2. shouldn't matter
3. guess you can
4. yes [I would just do that]
5. I don't think it will matter which way, they cant go far..

Maybe use some non hardening sealant on the gasket and around the bare part of the thread on assembly. Check and make sure the flanges are flat.


 
Use the lock tight it will help stop seepage. I have heard that the bolt holes should not be chased unless truly necessary. I would use about 35# torque and buy some safety wire at your local auto parts shop.

I agree with JSeery in that 35# seems like a lot of torque. Ya ask me? I think you are over thinking this one.
Ford ran a wire through all bolts. That photo you posted appears to be factory as you'd suggested. I would use mechanic's wire. It's cheap at about $2 a roll. I would most certainly wire them (bolt heads).
I would not use lock-tite. If it makes you feel better use a little Permatex #2 on the threads.
You may chase the threads you are working with. The threads you must never chase are those that are used to fasten the axle housings to the gear center section.
