I just replaced mine last year or the year before that. It was difficult to find. I eventually bought one from Rockauto that was a remanufactured unit. It works nicely however when they reassembled th ...

Wow what a build!!! That is a lot of really good fabrication.

Did you use the 1978 chassis for the build? I think I read that....if so how tricky was converting the chassis to a hydraulic clutch? I ...

Looks like a 924S or 944 tub since the rear side window was different on the 968.

944 had a fuse box under the hood. I dont see one in the pics so I think its a 924S.

Hood and nose/header pane ...

I am in the same situation. I have rebuilt an engine with NOS euro pistons (9.3:1), bearings from Ideola, everything balanced and a refreshed head. The extra power was barely noticeable. I also spent ...

Changed the booster with a remanufactured ATE unit. Fixed the low soft pedal. I dont understand why. Everything I have read about a low sinking brake pedal points to other issues. Even the little trou ...

I have my '79 block that I could measure. The block was align honed when I rebuilt it. Not sure if that makes a difference. I only have calipers to measure. Would that be accurate enough?
