This is described, with illustrations, in the Pantera Service Highlights (sect 4), lIght blue cover, available from some vendors or in the POCA Archives as a downloadable pdf for members. Not in the manual: If you've never done this job, it can be a real problem for one person. First, the ZF alone weighs about 155 lbs and the bottom is often slippery with seeping 90-wt. There's an opportunity to really hurt yourself or your car! And if you drop it, the costs can be enormou$. Get a garage hoist or two large friends to help wrestle the ZF backward and out over the sides of the engine compartment. If you choose to pull the bellhousing with the ZF, the wt goes up and so does the length and awkwardness of the package.
If you only pull the ZF, remember there are two large metric allen bolts inside the bellhousing that help brace the dash-2 ZF. With a transition dash-1.5 ZF (pushbuttons), the allen bolts are not there but there may be bracing arms between the early bellhousing & the early side plates you're trying to get to. There are two tiny 10mm bolts under the car that fasten the bellhousing to the bottom of the engine motor plate that's sandwiched between the bellhousing and the block. The ZF must first slide backwards about 6-8" to get free of the clutch disc splines; then it can be hoisted out. Good luck.
