After looking at my mounts the rear gearbox mount looks good as does the mount by the pulleys the only one that gave of slight concern is the rubber in the stabiliser/mount at the front right attached to gearbox but can not find the part number anywere is it a mount or stabiliser or something else

1997 escort 1.4 cvh 8v

The problem is the engine jerks when pulling away quickly or lifting of gas quick

Please help want to get it sorted this weekend but cant find part
