Be careful to use the correct parts when replacing the front shocks for 

classic cars such as the 1958-63 AMC American.

 There is a chance of breaking the lower control arms with the wrong shocks.

 The factory set up used 2 steel spacers that fit inside a rubber bushing:

 these pieces with their serrated edges lock into place when torqued to 110 - 125 ft lbs. 

thank you to Doug Galvin @ Doug Galvin's AMC for the information.
