A leather belt can be used as a makeshift strap wrench. You can also buy a strap wrench for a few bucks if you want. They are usually a rubber strap. The function is to add grip,.. fold the belt in half to make a loop, put the grip end in the loop, think of the loop as the box end of a wrench, slide your hand up the belt to the loop and use your hand to squeeze it tight, then turn.
End caps on both...
Rubbing alcohol correct....
Bar end weights are not stock on a Savage,... they screw on. Most bars are not threaded on the end, so many aftermarket bar ends have an expanding mechanism that fits in the tube and is tightened from the end.
You must get them for 1" bars to fit the Savage...
