Sorry to hear that.
If the LC engineering system looks stock, that would be easiest. The GM system would be the best but it wont pass visual smog. I ran the GM system on my CJ7. Massive improvement over stock. When it came time for smog, i just swapped back the crappy ford system they ran. I could definitely tell the difference. If you wanted to run the GM, just keep the old parts for smog and your good to go.
