    It has been done in the car...absolutely the hardest way to do it. Look at the lack of room by the harmonic balancer. You have to get that off, do the chains, and get it back on. The exhaust in the rear? Look easy???

    Drop the cradle...it's the easiest way.

    There are plenty of threads about doing HG's.

    You were asking about this a couple of months ago. If you try to do it in the car it is VERY hard. If you pull the engine out the top it is very hard. If you drop the cradle it's still hard.

    Dropping the cradle is still the easiest way. It looks scary but it makes things easy to get to. If you never did any major mechanical work I'd think twice about doing it. It is a long tedious job...not overly difficult, just a lot of work. Do you have perseverance?

    Most guys disco everything but the cradle bolts, lower the cradle on blocks or jacks, pull the cradle bolts, then raise the body with an engine hoist. It is not as hard as it seems. Then everything is pretty easy to get to.

    The only drawback is you have to disconnect the AC lines. The brake lines stay together.
