Unhappy buyer .What to do ???

Hey man,, the fact you are concerned shows your sincerity,,

What you have is two different diff builders, with different opinions,, but nothing changes the fact they are - - - as others have stated.. sold as used gears that have openly been used at the strip.... where we ALL go, to try and break our vehicles..

Sleep well,, you've done nothing wrong... let the diff. builders fight it out !!
