Oh man, this reminds me of the first time I changed the starter motor over for my van. The thing was awkwardly wedged and I had such a hard time wriggling the thing out.
Changed over and pleased, I drove to college the next day and dun dun dunnn, cut out and broke down at the front of the queue at a busy roundabout. Safe to say I wasn't anybodies friend that morning.
Been there. Done that. I can still hear the horns.
Trust me, I'm a doctor.
