I am restoring a 1971 campervan (probably a Sopru conversion? not sure?) The side (middle) sliding windows were manufacture by Qualicraft (NSW). The windows appear to be in reasonable condition other than the old rubber seals. I am trying to locate suitable replacement rubber bailey channel seals to accommodate the sliding glass. The bailey channel is housed in the aluminium frame channel - approximately 14 mm wide by 10 mm deep. Clark Rubber seem to have some bailey channel - but not this size. https://www.clarkrubber.com.au/search?q=bailey channel Does anyone have experience refurbishing this style of sliding widow - and any suggestions on who might supply suitable bailey channel rubber seals?
