I believe the linkage works out just fine. I had it hooked up prior to the engine/tranny install. I was able to use the stock tranny support because of the dirty dingo sliding brackets. That is basically how/why I decided to position the engine where I did.
As far as the shifter, I googled endlessly but could not find an extension/adapter/etc. I was going to either cut a slot in the aluminum plate like the stock pattern, or maybe just bolt the stock plate to the aluminum, and find some sort of rod that I could bend and either union onto the stock shifter with a bolt or just weld it together.
If all else failed, I was going to look into a cable shifter which I initial was against because of the cost, but now that I have re-googled it, looks like they have some NP241 cable shifters for $200 (for jeeps will have to read more to make sure its compatible).
Hell at this point, $200 bucks is easily worth it, with the limited time I get to work on it because of the baby. I can make more money, but a 3 or 4 hours trying to fab up a shifter is hard to come by.
So to answer you question, I think I am going cable shifter, my even swap the tranny over if I am going to go through the trouble of doing the tcase.
