Well, I don't know what you mean by crooked, but mine sits with the front angled toward the right [starboard] side. The exhaust is very close to the steering box and may be why the thing is off-set. Since the tranny is in-line with the crankshaft the tranny is also off-set as well as the tail shaft. The tail-shaft is centered between the rails but angled towards the left rear. From there the universal joint allows the drive-shaft to go straight back to the diff. There is sideways correction at the front universal that we wouldn't have if the engine was sitting in line with the fore/aft axis. Doesn't seem to stop all the tire melting and rather abrupt forward acceleration from stop lights so no worries.
