Unhappy buyer .What to do ???

I,m guessing the 7 sec. passes were 1/8 mile.My car is in the 6,s with footbrake(1/8 mile).

Ink,I,ll let this go for abit til it gets into a trainwreck.Which we all know it will.

Hope a lesson has been learned on buying used race parts.Been there myself.
I am truely sorry about this ,and i didnt want it ugly .I was seeking advise on what to do at first (because i have never ran into this situation before on here) then it turned into something else.As far as im concerned the deal is over and done now.Im moving on .If members think im "Shadey "then so be it .I have bought and sold many items on here over the years i have been a member ,and i always send the goods or the money when i say i will ,and i always represent items as best i can ...
