I have a nice old APCO spring loaded radius rod cap assembly with new spring and insert. When installing these were the standard pan studs and springs used ... or shorter studs and no springs?
Studs or use bolts with drilled heads and no springs. Tighten them up and secure.
Yes. Ditto to what John said. The adjustment is the one slotted bolt head on the APCO assembly that tightens the spring loaded 1/2 cup against the radius rod ball. Great period accessory. The APCO ball cap assemblies come in various sizes and I have them on all of the ball connections on my T. They do need to be greased occasionally. Jim Patrick.
So you are using a bolt with a drilled head. I guess you also use a lock washer .. and then run a stiff wire in the bolt heads just in case. Thanks.
Lock washer or not, the two bolt heads should be wired together.
When safety wiring bolts together, thread the wire halfway around each bolt, clock-wise, so that when the wire is twisted, the wire tension, tightens, instead of loosens the bolts. If you donít, you might as well not even safety wire at all. Jim Patrick
