I just purchased a good housing and tower with a shifter, along with many good parts, enough to be a complete assembly. I have most of it apart, needs a main cluster, reverse idler, and probably the large sliding gear, along with the usual bearings and syncros etc. I have only done model A' transmissions so this is new to me. What are good sources of parts, either NOS or good replacements, and where can I get a schematic of the trans with its parts exploded - possibly a step by step instruction as to how it all comes apart and then back together? Thanks in advance for any help. Steve
