Not impossible but extreme PITA. You wont be able to go from the bottom so the top is the only solution; unless you lift the car high enough. Removing engine mounts, accessory items etc. I would definitely recommend a lift or you will be cursing yourself for a long time....but it can be done with a lot of patience and knuckle busting.

I replaced everything without lifting the engine. Had to replace the Head Gaskets and left the engine bolted to the mounts (Wish I woulda replaced the mounts at the time though). I ididn't use Jackstands either :)

Only thing I had to do specifically to install the Long Tube Pacesetters from up top was remove the steering linkage and pull the DipStick out. But I also already had my Alt/Power steering/AC removed for the passenger side.

Dont forget though, the LT's might bump the sub frame so good idea to replace the mounts with Polys (earlier statement :D)

Thanks for the feedback, looks like ill tackle it with the car as high up as i can get it and if not, ill try going thru the top, its gonna be sketchy for a few days after install because the exhaust will get done a few days after (gotta wait for some $$$) so i guess running open with the off road Y and a turndown will have to work for a day or so, haha
