go to a spares shop and see if the part numbers are the same
I feel that it will be the same but due to the vagaries of engineering you have to check first
are you positive that it is the clutch as a faulty master cylinder will cause the plate slip giving the same indication as a failing clutch
Sounds like a gas tank full of crud. Check gas filter to see if it is dirty. Also water in gas will clog gas tank filter then when car stops water will disburse and collect when engine starts again.
