1. What car does the 6:29 R & P come out of and are they hard to find?
I don't think it was standard in any car, so they are somewhat rare. Pretty sure I got mine from Carquip.

2. What is the big plus of the small fuel cell? Is the weight savings that significant? Or is it easier to move it to where you need it? Or somehting else?
My fuel cell shape means I can run it nearly dry on the track without so much as a hiccup. The only other options are 1) converting a stock tank, which still has the weight up too high for the most part, is much larger than necessary for sprint races, and sloshes a lot; 2) a rectangular fuel cell in the front trunk, which is also too large, sloshes, often requires 2 pumps or a full load of fuel, puts the weight too far forward so the balance of the car changes as the level drops, and no room for an oil cooler in the front trunk.
With the smaller fuel cell right where I want it I can put more ballast on the passenger floor and have a better balanced chassis for the entire race. The CG even improves as the fuel level drops.
Each of the advantages I created is small, but added together they are significant IMO. OTOH, I've never seen anyone else do it this way, so maybe I'm all f*cked up.
