The new Melling M-68 STANDARD punp took me about 90 minutes to install. I did find an oops(mine) - so it turned out to be a good plan to replace the pump. The existing -A302 HD SVO oil pump drive was in backwards, not allowing the distributor to fully seat - which answers the original question as to why I felt that I did not have enough insertion into the distributor drive. Also am now using the -B302 later version shaft with more hex on top.
Now I have to take the vacuum advance off the dist - between the A/C compressor and alternator on Street and Performance brackets, do not have enough timing adjustment. So much for paying the extra bucks for the MSD Billet small diameter vac advance distributor. At least they supplied the material to do it.

Also, back to getting the body ready to paint - lots of separate pieces on a
Model A, but it is still a fairly easy to disassemble/paint/reassemble body.

Plus the spring honeydo's are waiting.

I do understand about grandchildren - our 4 kids have been able to present us with TEN !!! so it does get a bit busy around here occasionally. Unfortunately, the closest lives over 200 miles away in NJ, the furthest in England. Thank goodness for email.
