Does anyone make an adapter to mate a 727 to a 232 6cyl with the flat flange crank? I've had no luck finding one so far. Thanks in advance

If you don't mind me asking, why would you want to?

AMC did, in fact, manufacture an ADAPTER for the CRANKSHAFT 

It was made for exactly what you are desiring =
Mopar Style TF-6 / TF-8 (727 / 604 / 998 / 999 
to a FLAT-FLANGE AMC Crankshaft 
it basically was machined into the FLAT FLANGE area to place the FLEX-PLATE locating FLANGE 
where you need it for an AMC / MOPAR 727 etc FlexPlate 

I'm pretty sure ANY competent machine shop could reproduce these DIMENSIONS

It was a PRESS FIT after machining your Flat-Flange CRANK

The flange adapter is a partial answer. How do you bolt to the 71 and earlier block?

the FLAT FLANGE Crankshaft ADAPTER will work on ALL ...  AMC Flat Flange CRANKS

ie: 290 / older 304's / 343 / older 360 / older 390 / & OLD six cylinder engines / 199 / 232 / 258 / 

TRANSDAPT used to offer an  / ENGINE to Bellhousing adapter for older AMC  I-6 cylinder engines 
to
NEWER TorqueFlyte   Auto Transmissions  

the BellHousings on ALL  AMC  V-8's will fit the TorqueFlyte & 'GM' Turbo type Auto-Transmissions 

The  AMC  I-6  bellhousings were  before  <1972  &  >after 1972

Well I bought a 75 jeep DJ-5 that has a 232 mated up to a borg warner m11. I want to slowly work towards converting it to 4 wheel drive and I already have a 727/dana 300 combo lying around. So an adapter of some kind would be the cheapest/easiest way of going about it.

The adapter shown above is only for the flex plate and torque converter.
You still have an issue of the bell housing and starter on the left. If there was one made it probably wasn't many 50 years ago. The popularity code on that engine had to be " you're kidding me, right?"

where to purchase an adapter:
 
AMC originally made these adapters - NOS (New Old Stock) is always a possibility 
... maybe the KENNEDY's in FLORIDA ?
the best bet is to befriend a machinist with a LATHE or hire it done in a machine shop 

You could always do a GOOGLE SEARCH by the old AMC Part Number listed several POSTS above ... 

AMC  Part Number:     321-6130     

+++++++++++++++++++++++++++++++

As far as the 1975 Postal  DJ-5  with a I-6 cylinder AMC (regardless of Cubic Inch)

This crankshaft should already be set up with a FLANGE  
but
You mentioned that "YOUR" 6-cylinder AMC  I-6  was mated to an
OLD  Borg-Warner Automatic transmission ???

I was a USPS Letter Carrier for a few years in the mid-1970's & I would bet my LUNGS that the POST OFFICE did  ... NOT ... use the antique BORG-WARNER Automatic transmission

I beLIEve  that Borg-Warmer stopped making the M-11 & M-12 when AMC / JEEP switched over to the TorqueFlyte transmissions in 1972

So ... if YOU actually DO have a Borg-Warner auto-tranny = my BET would be that someone along the line did an ENGINE / TRANSMISSION swap  into your  1975  DJ-5  

IMHO

I guess the easier question on an oddball vehicle is which side is the starter on?

The starter is on the left side of the engine if you are facing it from the front of the vehicle.

As for the postal Jeeps the research I've done into them says they continued to use the borg m11 and m35 until 74 with 75 being the changeover year to the 727. 

My guess would be AM general got handed all the left over stock when AMC made the switch and continued to use them till the stock ran out.

Then it's a right hand starter.
1/3 of the way there. Now to guess the bolt pattern of the trans and what crank.

just an  FYI  from my RACING Days 

I have used a 258 cid  I-6  Flywheel 

On my V-8 AMC's  because, I beLIEve they have a NEUTRAL (or a more 'neutral') BALANCE

So ... my best GUESS would be that the Manual / thus the AUTOMATICS would have

The SAME Bolt Pattern ...
