I recently tore into my engine to do a full rebuild on it. I found some interesting stuff in there. A rebuild tag, some flat-top pistons that have nothing, and I mean nothing, on the top besides .75 stamped into them (.030"/.75mm over) and the crank was balanced and cut to .010"/.25mm undersize. What I need is some help identifying the pistons. They are definitely cast but almost the entire outside of them is machined and it has vertical slots machined into it every half-inch or so on the piston

Ok so lastnight my transmission started whining really bad after i raced a car. Its full of fluid and shifts perfect. What could it be thats causing this. This transmission was recently rebuilt and has about 5-7000 miles on it.

I need the screws that hold the radiator grille on. I'm willing to pay a few bucks through paypal.

Looking for a keyless entry for my suv. Something with extra channels and remote start.
