I got a 82 K5 blazer. Originally a 305 but now a 454. I built it for straight line drags but my home track has closed and now I am trail riding and I keep breaking stupid little things. Who is a good place to buy used parts? The running gear is original stock 350 trans with stock t case and adapter. Last trip out for Halloween ride I broke the adapter between tcase and tranny. I figured out I need to reinforce it but I need to buy a replacement and I cant find one locally. Any help would be appreciated. Thanks
