Which exhaust flange do I need? (BCR 4-4 pipes)

I shot an email to Benjie asking for clarification on which exhaust flanges to use for the pipes he made for me, but while waiting for his reply, I just wanted to see if anyone else that has his pipes might be able to help me.  What flanges (part numbers) did you use for your BCR pipes?  In one of his earlier communications with me, he said to use a '75 - '78 CB750 flange, but from what I've seen on the schematics, they're different for a couple of those years.  Maybe I'm just looking at it wrong. 

Here's what I'm working with:

Hopefully if the stars align right, I'll be putting the 1,000 pieces of a bike I have back together and will have something to ride within the next few months.  :o  But yes, they do look slick... even just sitting in the box!  ;D

looks like not the spigot type but the type with the finned collar and 8mm studs in the head.  You will also need the split keepers that go with it

Btw, here's something for you Steve... a shot of my pipes being fabricated.  :)



Thanks for the info Toxic.

Lokks like this might be the set up for those. Auction ends tonight  ;) http://www.ebay.com/itm/Honda-Motorcycle-CB750K-Exhaust-Pipe-Clamps-Shims-1978-CB750-more-set-4-/250972717583?pt=Motorcycles_Parts_Accessories&vxp=mtr&hash=item3a6f23c20f

Thanks ekpent.  I'm going to do a little more looking around today, but I'm definitely going to keep an eye on those!

I have the same exhaust.  You'll need exhaust flanges from 1976-78 cb750 F models.
