So this thing has them "sort of" installed. The alternator pulley was left off. I have hear these cars have charging issues, and that is what the reasoning was from the previous owner. BTW this is on a 88. Sould I install or leave the way it is? Thanks.

 

The difference in size between a UD alternator and the stock part is so small I don't know why they even sell one.
I've never had any charging problems using UDP's but if your alt. or battery is weak or have a huge sound system it might cause a problem.

Change it or not,it's up to you.
