Found some shiney things when I cleaned the dirt off

I ended up needing to get a new battery for the car as the old one was well and truely dead. I got it fired up (WOW) and it started making some horrible squelling noises (Oh No!) I quickly diagnosed it to be the one or both of the fan belts. Today the plan was to get the fan belts off, take them to the shop for size comparison and get new ones. I went to slacken off the power steering pump to loosen the belt and this is what I found!

Someone didn't put the washer back on benind the head of the bolt. As a result, they'd tightened the bolt into the slot!. I tried everything to get it loose, sockets, breaker bars, spanners, vise grips. As a last resort I used a screwdriver to lever the bracket over the head of the bolt. It worked and I now have a washer fitted!
Well the fan belts have been replaced and I changed the plugs. I also swapped the carbie off the motor for the hotrod. Now you turn the key and it starts first go!
Next step is to try and find where "R" went in the gearbox.
