I have a Pearson 10M with an A4 installed. I purchased a second A4 and am in the process of rebuilding it. The motors will be swapped when the rebuild is complete. There are many newer parts I installed on the running A4 and I am trying to avoid buying the same parts. I am in need of an exhaust flange and a thermostat housing. They don't need to be in pristine condition as I can swap them out once my engine exchange is completed.
