I just completed a two year restoration on a Pontiac GTO.  There were many obstacles to work out on just about every aspect of the restoration, but by far, the best experience I had was with Keisler Engineering!  I purchased a TKO600 5-speed and hydraulic clutch set up.  When it arrived, the box had been damaged in delivery.  I called Richard in tech support and told him I thought I may be missing some parts and he sent me the next day all of the contents in question!!  I was floored!!  He sent me extras to ensure that no matter what, I was covered!  I got it done and the transmission is amazing!  I got everything I paid for and more...and that is pretty much unheard of these days!  I think Richard and the rest of the crew at Keisler should be commended.  They provide a great product and back it up like they still own it.  Thank you for everything!
