Am going to put a 413 T/c into a friends 410 . Apart from changing the drive flanges over is there any other traps like the speedo etc . don't need the speedo conected if its a problem but would be good to keep it sealed up etc .
Change the flanges. If you're not changing over the e-brake drum you'll lose the emergency brake. The speedo cable is the same and should swap right in. I believe the mounts and everything else are interchangable.
