I’m looking at pass side alternator mounts for my 2001 LS1 swap and I’m seeing 2 options ICT and dirty dingo. Looking at the 2 the difference I see is the ICT uses and idler pulley and the DD does not. What are your thoughts on this, is the idler pulley necessary ? The price difference between the 2 is only $20 so I’m not leaning more towards one based on the price. I do think the DD looks a little cleaner without the idler pulley so if it’s really not needed I’ll probably go that route just based off the looks.
