Graeme, great work on cleaning up the front end components. I noticed that you replaced the end link hardware with NOS parts and this may not matter, however the end link bolt with the WB (Wales-Beech) head marking used on 69's was a Grade 3 bolt with fine threads. For some larger GM vehicle applications the bolt used was instead a Grade 5, with 3 radial head markings as shown on your replacements, which is also course threaded. The correct bolt has no radial markings.
