hey, that's better. I would say the diff is mid '80's camaro because of the 2 big bolt holes for the link to connect the diff to the raer of the trans, some sort of traction control bar set up.
not sure on the front end because I am not the front clip guy, but for sure you gotta take the steering box off (without turning it so it has a chance to suck up any dirt), tip it upside down and flush out those hose connections with some brake clean or some other solvent. see what you have after that.
not too sure what the large lump of metal is on the frame by the rear wheels either but would say it could be a tire biter.
