I don't know about the driveshaft, it's was a tight press fit, coated with JB weld and seems pretty strong: see how it holds up. I am a little concerned with the 550 in there, but fingers are crossed.
Chassis is pretty much built, just need the valences front and rear. Then, tearing it all back down for finish work and painting it all black.
New upper deck in place
New front shock tower brace/body mount. Note the 22t 550 truck motor stuffed in there. Should be plenty of torque to get the wheels spinning.
New rear body mount/shock tower brace. A bit of an odd size due to the body.
Stripped the stickers off the body, looks much better!! Not sold on the wheels at all, think I can find something better.
