Engine needs rebuild. Looks like it has seen some trails.

“Complete CJ2 jeep Needs engine rebuild. Drive train is good. If I don’t sell it as is I will be asking $6500 with a rebuilt engine. Not sure on the miles. On non opp and title in hand. floor boards are not rotted out. The engine has been sitting for years with the cylinder head off. so the cylinder bores are rusty. The pistons are most likely stuck in the bore. my asking price is firm.”
