I forget the change point offhand, but the factory quit fitting the valve at some point, either during TR4 or maybe when the 4A was introduced.<br>-- Randall<br><br><div class="gmail_quote">On 6 November 2019 12:19:21 GMT-06:00, Jim Henningsen <trguy75@gmail.com> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
