Cad plating
Many years ago when I built my last club race car I had all the high tensile bolts plated (silver colour though). I was informed by the plater or the bolt supplier or a random stranger (  , as I cannot remember whom) that this process induces stress in the high tensile bolts and should be stress relieved.
To do this you need to heat to 200 degrees C for a couple of hours, again if I remember right. I did this.
Anybody else have any knowledge about this. I'll make a new thread in the restoration section ...

Yikes. I definitely wasn't planning on that. I hope everything doesn't fall apart as I'm going through turn 8.
If anybody else knows anything about this, please let us know.

See this thread: Plating high tensile bolts, it's called Hydrogen embrittlement.

Also it might not be required:

Your plater should know what is required, especially if he cad plates for the aviation industry. Just ask him if he passivated all your parts, and if not, why not??? The Mil Standard that they should have been done to is QQ-P-416. If they were done to MIL-STD-1500, then they probably weren't passivated. -1500 was superceded by -416. -416 introduced the passivation process to prevent embrittlement.
Hope that helps.

Thanks for your posts - just what I need to get me out of the post-Christmas lethargy and starting my restoration ....

Those black minilites with the polished rims look great!! I don't suppose you have a bigger photo of that car do you Colin?? I'd like to photoshop it to see what the car would look like in French Blue.
Very very nice car

Hey Max, if you're reading this, please post a pic of a 105 on black panasports.

You know how sometimes you just can't wait to see how some things are going to look? I wasted about half an hour putting a wheel on to my freshly assembled 4.10 rear end, just to see what it would look like. So now I have to take it back off and get to work.

There are a number of pix of the Alfaholics car on their website, in the competition reports section - I've attached one below...
