I just finished putting in a Duralast 305258 serpentine belt tensioner four a four rib serpentine belt that drives a supercharger, an SD5H09 compressor, a CS-130 alternator and the water pump. The belt no longer "chirps" when the AC compressor is turned on. There is zero squealing, even when the engine is cold.
The installation is very easy. All it takes is two standoffs (PN 460-320) and a generator adjusting link (PN 460-330).
The standoffs are bolted to the front plate and the engine mount bracket. The long threads on the standoff are on the back of standoff.
The link goes on the upper standoff.
The tensioner is bolted to the lower standoff and the hole in the link. Two washers on the lower standoff make up for the thickness of the link.
It doesn't take a rocket scientist, but it helps.

In reply to # 4759874 by dickmoritz
It appears that you have a front engine plate from a rubber bumper MGB, with no mount bolts installed. How is your engine mounted to the chassis?

The engine is attached to the frame with two drops of unobtanium.
No, really, I have no idea as to what you two are talking about.
The engine mount bracket is bolted to the front flange - as seen below - and a second engine mount bracket bolt is bolt is bolted to the engine block.
The flange bolt has been replaced with a standoff, but the engine mount bracket is definitely bolted to the front flange.
