<div dir="ltr">The "packing pieces", or shims, go between the firewall and master cylinders. They move the master cylinders forward which then moves the pedal arms forward resulting in the pedal foot pad being lower. This way you can adjust the clutch and brake pedals to be at the same height. It does not change the stroke of the master cylinder in any way.<br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 9, 2021 at 11:31 AM Simon Lachlan via Healeys <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-GB"><div class="gmail-m_5910726119007090290WordSection1"><p class="MsoNormal"><span>Certainly 4 are shown in my parts book, so suitable for MkIIs.
