L67 Bolt Stripped

[BoostedL67]

Allen Key bolt head stripped out on L67 twin smooth pulley. Tried most things, snapped a few ezi-outs in there and have had to drill and drill. Is this a stock bolt or has someone been dodgy? I know that another pulley bolt has been replaced with an incorrect thread. I have only just bought the car and know nothing of it's history. I am trying to change the water pump. Any advice would be helpful.

Is the whole mount replaceable?

Under the DFI module? Yes its replaceable

Thanks. Also can you tell me if that bolt that holds the two pulleys on is usually an Allen Key bolt or has somebody replaced a Hex Head with it?

Can't remember off the top of my head. Can check when I get home if you need.

That would be helpful.

According to google images, some have the Allen bolt there. Could be factory.

Mine is the original and it has a torq fitting I believe.

Oh. Mine has been changed if that is the case.

A new mount is around $35 from Holden. It's a inner torx bolt too
