Thanks for posting.... forgot about this good idea!!!!
One of the plans I have for the Opel is to switch from 10" rims & tires width to 12".
Since I got the Opel late last Summer I have been kicking around the idea of
removing the rear fender flares for a more authentic "gasser look".
Whoever installed the rear fender flares did a GREAT JOB doing so. They look like they came from the factory.
So another one of my "plans" will be to remove the flares and while I am at it relocate the leaf springs inboard and make new mounts for the rear shocks which will attach to an additional crossmember that will be added to the rear of the frame.
