Write your reply.

assistant: I've never done a belt on a 2.2 or a 2.5 Shadow so I can't help you there.
From what you are saying it sounds like a lot more work then what my old '86
Ranger was. I broke that on the way to work one day and got it towed to work
and stayed late and did the job in about an hour.
I have also done some on Nissan Micra's and have taken anywhere from a couple
of hours to 3 days, depending on when they broke, or if they broke. They were
a pain cause if they broke they liked bending at least 4 valves and sometimes
they would damage the head which ran into big money.
Hopefully you'll be able to wait for a little bit longer until th weather
turns warmer :) So where are you at? I know here in Halifax,NS, it was nice
last week but it decided that winter was coming back the first of the week.
Anyway, good luck and I look forward to hearing how it turns out for you.
