No idea how long these have been out but it's good news for anyone doing a rebuild :D

But nobody has WBX big end bolts. Desperately need at least one set.

I was advised that the non-stretch type are fine. VW Heritage have them here.

Thought about it, but the whole point of angular torque setting and "stretch" bolts is to achieve much higher clamping forces between the rod and cap than can is possible with static torque bolts/method.
This makes for a more stable bearing journal and afaik all "modern" engines use bolts of this type and angular torque setting.

Still none available anywhere. Hope its just due to restocking and the August shutdown in the Vaterland.

Not sure. I have managed to find some rare parts out there that were NLA in Europe.

So what's so unusual about them? Is there a reason that they can't be substituted for stretch big-end bolts off something else?

Not common with any other engine. Unique combination of lengths, diameter, design of head etc.
I have tried modifying rods to use 3/8" BBChevy bolts from ARP but the interference fits they use are mental. They actually stretch the big end out of shape, unless I fitted them all wrong.
I am not convinced that the cap location is correct either.
Earlier Porsche bolts may be an option but I have no experience of them.

I once bought some Audi parts from Notter, showed stock and paid only to get a full refund within 24 hours.
Will give them a go though.

Ordered a few sets and will see what happens.
Thanks for the tip-off.
