Hi bopnz,
Most cars in the usa are closed cars not open top like ours,probably why no one replied.Suggest you advertise in Restored Cars or the like or watch Ebay Australia.Occasionally one comes along and you may be able to graft them together.There is a difference between the 27 to 28 chevs but not sure from 25/6/7.Jackson is back making panels again and of good quality like normal.Spectrum rubber took over Jacksons original business some years ago so maybe both can help.I have Jacksons number and address.He now trades as Old Era Services P.O.Box 3048 Llandilo NSW 2747.email oldera@jackson-s.com.Ph 0245725621.
Spectrum rubber advertises in Restored cars.
See how you go.
