they can be pretty dang rough before I can't fix it, I had to fix a set for a Starsky n Hutch type car because they were impossible to acquire but the set ended up costing about two hundred bones each.
I felt sorry for the fellow due to cost but i needed to get paid for my effort, I told him the cost before starting and he said go for it.
They looked very nice when finished and he couldn't have been happier.
