Who has best deal on the following parts ??

You can get a walbro 255 inline for like 110 shipped. I got mine from some import place on the internet. The only difference between that and the t-rex is like a 90* fitting. Heck walbro might even make the pump for t-rex, they make them for everyone else.

Far as your 6a goes i would check on ebay, same with the wablro... its like GSL 394

my local swap sheets usually have MSD boxes for cheap, you could check those and save on shipping.
