    These adapters were installed on 64-67 Dodge A100 and A108 trucks and vans, as well as in taxis, cop cars, and other fleet vehicles that used a slant six. I need the adapter as well as the crank spacer.

    I need it to be fairly close to the Puget Sound area since shipping will be expensive. THe cheaper the better, the closer to Tacoma, WA the better. Any leads appreciated.

    Here you go: a heavy cast iron sucker to mate a slant to a 727. I’m holding this one until it’s paid for by another member who bought it when I had my slant sale

    Hmmm. I knew they put 727 behind the slant 6 for heavy service vehicles, but have never seen a 727, slant 6 case. Now I know why.

    Slant six 727s are actually fairly comon in 68-up trucks and vans. I have one right now in my 76 D100 and I have had several in the past. THis adapter was used only from 64-67. In 68 Chrysler finally made a 727 case for the slant. Prior to that they just used the adapter and the smallblock 727.

    65 Dartman- if the purchaser backs out, I would be interested. That is exactly what I am looking for, except shipping from VA to WA (even though it is just a consonant away!) might be cost prohibitive.

    FYI
    There were 2 different crank spacers, depending on the year of the transmission, and torque converter being used.
    Depends on the diameter of the "snout" of the converter, to the crankshaft.
    So be aware of that, if your not, already.
    Also.
    I too have an adapter, but no crank spacer.

    Right. The slant six crank pocket changed sizes in 67, along with the snout on the torque converter. The good news is that if you get a 64-66 crank spacer there is an adapter ring for the crank to allow you to use a later engine to the earlier trans. The torque converter end of the 64-66 adapter could be machined by a competent machine shop fairly simply.

    So they did make a 727 Slant six case. Learn something new every day.

    I never got that far along with one of those adapters, in bolting it up to the back of an engine, and then mating up the transmission to the adapter.
    Due to the thickness of the adapter, wouldn't you run into problems in trying to bolt down the transmission into the rear crossmember with now everything being longer?
    Was there a different transmission mount also for that set up?
    I always wondered about everything working, linkage, mounts, stuff like that.
    Sounds like you know lots about this stuff.
    Why don't you just go and find a slant 6, 727 transmission?
    Wouldn't that be a lot simpler?

    My understanding is the unit only weighs 25-30 pounds.

    The adapter is about 3/4-1 inch thick, so, yes, the trans sits that much farther back. However, there is about that much play in the later trans mount holes, and slack can be made in other areas.

    I want one of these so I can mount an A500 automatic overdrive trans behind my slant six. The A500/A518 was never made with the slant bolt pattern, only the smallblock bolt pattern. But Chrysler did make this adapter to mate a slant six to a smallblock trans. Everything old is new again.

    Remember that when the adapter was designed it was for the A100 series which did not use a regular transmission mount (installed under the transmission) but used a transmission that had a boss on top of the case to support the transmission from above. Kickdown linkage was also designed somewhat different than from the cars. Adapting to a car is not really a problem and has been done quite a few times.
