4.0 to gm nv3500

[Rusty Jeep]

Is there a way to adapt an AMC 4.0 to a gm style nv3500? I can find an adapter plate to make it bolt up, but I'm not sure how or if you can space the flywheel and clutch and starter to compensate for the extra 1/2 inch. Does anybody know if someone makes an adapter kit for this?

if anyone does, it'll be Novak or AdvanceAdapters.
