#1 The motor mount brackets go on the rear side of the ears on the drivers side and on the front side of the ears on the passenger side. 318's and 360's have different left side motor mounts i believe.
#2 71 and earlier small blocks had the timing tabs cast into the timing cover but on the passenger side. Not the drivers side like 72 up. So look down in the fuel pump area for it.
#3 Also before 72 they had a different damper on the engines that had one offset hole. This can be corrected with a round file. This is a normal and recommended fix by Mopar.
#4 can't help ya there.
I bet your engine has the lower water pump hose on the drivers side. 72 and later small blocks have them on the passengers side. If you ever want to change that then you need to change timing cover, water pump and damper.
