87 driven clutch spring

[didjidude]

I have an 87 2 stroke that looses power when going up hill. I believe it may be the driven clutch spring, I have taken the clutch apart and put it back together using only my hands (I think the spring has sprung). Problem is my local ezgo dealer tells me the only spring they can get is for a 89-93 driven clutch unless I can get a part number for the spring I need. I know they are still making the clutch which can be bought for a mere $250.00 (seams to me that that clutch uses the same spring.) Anyway does anyone know the part number for that spring or know where I can get one. A power spring for that year would be even better. Any help would be appreciated. Dave
