Yah, man, that REALLY sucks. Sorry to hear that. It's easy to beat yourself up for mistakes, but the truth of it all is that nobody's perfect. As mentioned b4, keep your head up. Try not to let yourself get too depressed.
Most of us know how it is to break something (even though maybe not to the extent such as this). Sadly, but good in it's own way (experience), that's part of the muscle car hobby-- to break things
. I'm just waiting for something to blow up in one of my cars--- one day or another
.
Hope things work out for you and you get your car on the road. Take it easy.
