Help! Rebuilding by 66 dart but im putting in a slant 6 225 bored out to a 227

so I have a 1966 Dodge dart and the engine Im putting in it is a 1965 slant 6 225 bored out to a 227 and I’m missing a few of the parts. It was my dad‘s car and he unexpectedly passed away halfway through rebuilding it so I’m lucky I found the parts I was able to, but I’m missing my distributor and my push rods and my oil pan bolts as well as my headlight bezzels but right now I really need help figuring out what size bolt I need for my oil pan and i want to upgrade my distributor to an electronic one so if anyone knows the bolt size and has any recommendations for the distributor upgrade, please let me know!

The oil pan screws, or bolts, for the Slant Six engine, Chrysler part number 1947943, are 5/16"-18, 13/16" long with a 1/2" hex head and a captive washer, ~9/16" in diameter. Twenty two bolts are required.

I perform point ignition to 1973 - 1987 type Chrysler electronic ignition upgrades using older NOS parts and/or good used parts from a donor vehicle. 1973 - 1979 wiring and actual 5-pin ECUs use the dual ballast resistor which can be used as is or further adapted to the single ballast resistor style. An old USA made Direct Connection or Mopar Performance P3690789 electronic ignition kit is convenient and well made if it can be found.

For more information on the Chrysler Elecronic Ignition system, see Chrysler Electronic Ignition.

My document is not a step-by-step conversion instruction but has the information needed to do it. The instructions from the P3690789 electronic ignition kits are available and can be used, although there are some areas that could use improvement in those.
