Timing Chain Tensioner - Koch Tools?

[superninety]

Anyone ever used Koch Tools and specifically their version of the Timing Chain Tensioners (supposedly the same as Porsche tool 9401)?

911 993 964 996 GT3 Porsche Auxiliary Chain Tensioner Tool Tools timing





Gathering tools to remove and reseal the cam chain housings on my 964 and this seems a possible alternative the factory tool.

Thanks.

Or I see people are using generic steering wheel pullers. Would love specifics on which exact tools work so I have it on hand and not waiting/searching once it's apart.
