Hi guys, really well in to a N10 restoration project. If you're interested it's #TetanusTruck on instagram. Right now I'm working on completing everything from the chassis down to a fairly good standard. One thing I know is borked is the rubber coupler that goes between the steering box and the column. RockAuto has no replacements for any Toyota of that vintage. Ebay has some for N20s that also fit first gen Celica. Does anyone know what parts are interchangeable here? It's really a matter of getting the same spline count for the connections. I bet it's a common part, but common to what?
