Direction of bolts on the driveshaft and the transmission flange

I was watching FCP videos and noticed that the mechanic installed all the bolts in the same direction.

Is that correct?

The instructions that came on my Febi Guibo says to align the arrows with the flange and the bolt should insert from the opposite side. The nut should be on the flange side. At the end, 3 of the 6 nuts and bolts should be in opposite directions. Looking to get confirmation.

My brand new genuine drive shaft came with the bolts on the shaft side.

You wouldn’t be able to install the bolts on the gearbox side the other way there is no room to get them in from behind.

So seems correct to me.

The arrows should point to a flange...bolts can only go in one way.

Comment on the disc, there is no front/back to the disc, but make sure the arrows line up with flanges, so that when transmission output flange is turning ccw (facing toward front bumper) and transfering energy into the disc, it is compressing the thicker/meatier part of the disc between the holes that attaches to the driveshaft.

Bolts all go in one way, easier to torque/hold the nut if you remove the tranny vibration dampener (hold tranny up with jack, remove the mounting bracket and mounts to slide off the dampener, mount the mounts and mounting bracket back on, then once done torquing the guibo, reverse). A bit more work, but I find piece of mind in doing that.
