We have a 1985 Acty that we have made into a coffee truck. We are having brake issues and also trying to find 12" wheels with a 4x120 bolt pattern (none to be found). It needs brakes so I thought I could purchase different drums for the brakes that have a 4x100 bolt pattern. Two questions, 1, Where can I find Brake parts and 2, where can I find brake drums that will work with the 1985 spindles? This would be a DYI project so I'm looking for some help. Thank you
