I have an off road only 73 Scout II with a 345 3 speed manual. I would love to change the trans to an automatic. What is the easiest and the most economical decision?

Thanks
 
Welcome. The most economical route would be to source all necessary parts from a cheaply purchased '73-'79 sii auto 4x4 with rotten body, but in running condition. Here's what you'll need:

*IH sv8 pattern tf 727 that has a married t-case adapter housing with Dana 20 auto bull gear attached.
*IH sv8/tf 727 flexplate and crank spacer hub plus bolts.
*1/8" metal spacer shim placed between starter motor and engine block, used only with the auto trans to ensure proper ring gear engagement.
*sii radiator with trans oil cooler fittings, or purchase auxiliary trans oil cooler.
*sii metal trans cooling lines.
*sii auto 4x4 trans tunnel cover, floor shifter and shift cable.
*sii auto brake pedal assy if desired - the manual assy will suffice with clutch pedal removed.
*all carb throttle to kickdown lever linkage and bracket pieces.
*sii auto trans cross member.
*front and/or rear prop shafts May need to be swapped due to potential differences in length.
*complete the necessary circuits according to sii with auto electrical schematic for proper neutral start system function.
