Hey Guest!
There was a number system used to describe "standard" fasteners. It is published in a couple of places. Unfortunately, a lot of Healey fasteners were not considered standard, didn't fit the system, & the parts book numbers give little clue to what the actual fastener is. Especially on the older cars. BN1's had a strange mix of different thread systems which complicates the issue.LuckyLuke said:I'm looking for an original or a copy of an original Austin Healey Parts book to support the restoration of my 100/4 BN1. In particular I'm trying to find the correct fasteners sizes etc...
