ARP Rocker Arm Stud Dimension Diagram - Stud Height & Thread Measurement Guide

This document is a small dimensional reference diagram for a screw-in rocker arm stud (uploaded as 'ARP Rocker Arm Stud.jpg'). It shows a photograph/illustration of a rocker arm stud with lettered dimension callouts (B, C, D, E, F) marked with arrows across the part. Below the illustration, an italicized note explains how to use the dimensions to verify the correct application and part number: B is the overall stud height, C is the screw-in thread depth, D is the adjuster thread depth, E is the shank diameter and thread, and F is the base diameter and thread. The document contains no year, make, model, engine, or part number information itself — it is a generic measurement guide intended to help a user measure an existing stud or cylinder head requirements to select the correct replacement rocker arm stud. A reader can learn which physical measurements to take on a rocker stud (height, thread depths, and diameters/thread sizes at the shank and base) when cross-referencing or ordering a replacement, such as for a small-block Ford engine in a 1990 Ford Bronco as claimed by the uploader.
