I have a 1979 T2 with a 1776cc engine and fitted with a Vintage Speed Sports Exhaust System, Standard Tail Pipe (AC251816). One of these: It's a long shot but does anyone know if the JustKampers Towbar will fit on my setup? The JK Towbar is the TÜV Approved Tow Bar VW T2 Bay 1973-1979 (J43906). One of these: If no, can someone please suggest a Towbar that would fit?
