You should be able to use any of them.
The one your pic shows is the big heavy cast iron one that weight like 15lbs.
Find the two peice aluminum riviera/h-body brackets.
They have a 1peice aluminum bracket for the SC tensioner and idler and an aluminum coil bracket bolts to it.
You can relocate the coils as well as have less weight.
Offhand,the regals also have the big cast bracket.
Have two L67's here,one for mine and one for wifes impala ss clone.
She's getting the heavy bracket
I can take pics of the two,they interchange I know since I just did it.
The aluminum bracket is great if your going to relocate coils,since the coil mount comes off.
, haven't got a chance yet.
