Need Early A-Body slant 6 Oil pan

robertop,
Thanks for the great info. Sounds like I shouldn't even consider an after-market chrome pan for my 64, since the steering might interfere, plus the pickup would be wrong (who would have thought?). I already de-rusted, knocked out dents, and painted my original pan anyway. As far as I know, the block is original, but the casting # appeared to match later years in a table posted here.
