C'est simple get the polaris connector they work the best so you don't have to deal with old school splitbolts let me put a photo so you can see what I mean.,,
I know it cost more than standard split bolt but you will end up save alot of time in long run due it is cleaner and quicker and also they are listed to use both CU and AL and they do come in few diffrent size as well.
This what I useally keep few in my service trucks it did pay more than once
Merci,Marc
