He didn't say where he picked it up from.
he's always picking up goodies.

A mate of mine has just scored a factory a series EFI manifold. All his datto's are either L6, or rb26 powered. So it's of little use to him.
Given the rarity of these, what is fair value in today's market?
I've heard of a price one sold for a few years ago, but that was before the downturn in the mining boom. And it seems that the stupid prices that stuff was going for back then aren't being seen anymore.

Any input?

I don't know about your neck of the woods, But the Aussie blokes seem to pay through the nose for either of these gearboxes. The 63a is the real Gem though. I'd expect one of those to fetch four figures plus in Aussie. If I wind up putting my car back to standard to recoup more of what I've spent, I'll be selling mine in Aussie. I'm a little bit closer to them that you though....

Keep that gearbox!
Or better yet, give it to me!
Sorry for your loss mate.

Sssssnake oil..............

They're a torsen, or "helical" LSD. Which is neither 1.5, or 2way.

I scored an RB box with noisy bearings for $20 from some flat peaker. Good score,
