Get the parts in advance.
I would buy from a junkyard, all parts attached to the same-type transmission in a same-type car.
I would make cardboard templates measuring where the holes
are for pedal and shifter.
With the new trans, buy the flywheel/pressure plate/disc and a new pilot bushing.
If you are in the Tampa Bay "area" and need a hand, pm me.
I might be interested, depending on my schedule.-Bob
