1975 911 S engine overhaul


Vehicle Information: Model: 911S; Year: 1975; Body Type: Targa; Total Mileage: 115000;

I am rebuilding this engine and have added the pressure fed chain tensioners and the mid 80's chain tensioner sprocket arms with the longer bushing.I have inspected the height of the sprocket to the sprocket on the cam shaft and found it is lower by 0.060 inch, the piston of the tensioner also is above the new sprocket arm. It appears that a 0.060 inch washer between the arm and the chain housing base would line it up.Should I do this? have I got something wrong? I am using used parts from Parts heaven, are there different sizes of arms.I am using A3262 on the left hand side.
