Altair 8800 restore details - Model B grounding scheme?

Back home now, the trip up north was great.. it got a bit cold, particularly out on the lake, but great never the less! The generally-available 8800 kit manual is for the original (perhaps 'A') version, which contains grounding scheme notes for the 'A' type power supply. My machine has a 'B' type PSU, and as such, may have some differences. Is anyone aware of any differences between the A and B type grounding schemes? Can anyone provide any documentation for the same? Also - I was able to come up with some 1/8" braid to create the several ground straps - but I can't find any 1/4" braid as spec'd in the manual. But again, the manual is for the 'A' series and the 1/4" braid is used on the negative end of the many (8?) electrolytics used on the A type PSU board. I'm not even sure if such a scheme is used on the B type board.. and my board bears no sign that such a scheme were ever implemented. But obviously, the board +must+ be very solidly grounded, so.. how was it done in the day? As ever, thanks for all of your input! The project is coming together nicely..
