Hi just trawlling the next on Mazda 1500s and spotted your question re unleaded fuel.
I have a '69 1500 fitted with a 1600 Capella NA block. I have been advised by both Mazda and Clayton at Mr RX3 (www.mrrx.com) here in WA that they run fine on ULP. However, I do put a shot of Valvemaster in every few tankfulls to be safe. Mazda suggested PULP too.
As for spares.... try Clayton and also the Mazda Collectors Register... Jonothan Barr mazdacollectors@aol.com or mazdacollectors@optusnet.com.au
