Car jerks when dis-engaging clutch quickly

Assuming everything else is ok, like clutch disk springs, gearbox, differential, and joints, maybe you should change the original rubber engine and gearbox mounts with polyurethane ones. Installing a torque damper also helps.

I own a car repair shop, and I never touched any 1988 Accord (I think I never even see any), but you should find these parts to buy in the US. Here in Brazil, we often make this mounts by torching the rubber off the metal part and press pushing a polyurethane insert in it.
