Has anybody run into an issue with a 2009 DD15 being too long to fit into a 2010 Cascadia Day Cab that had a DD13? Had a customer bring in a 2009 Cascadia Sleeper that hit a horse and a 2010 Day Cab with oil starved motor. Removed both engines and when seated in the rear mounts the DD15 sits too far forward to bolt up front motor mount. After measuring everything it looks like the Day Cab frame is shorter from shock towers to rear mounts. Rear in frame mount is as far back as it can go without drilling frame. Measuring the DD15 engine we found that it was between 1-1/2" - 2" longer than the DD13. About 1/2" of that was in the Bell Housing. Any info on resolving this would be geat. Or if you have tried it and it became a "Custom Installation" that would be good to know.
