SLEEPYS 69 swinger project

It's amazing! You really don't get the full effect of how far it's come until you go back & look at the charred burnt mess you started with! My hat is off to you not only for your skills, but for your courage & ability to see through what most of us would consider beyond the point of no return & to see it through.

Can you shed any light on the '73 fender used? What mods are necessary?
Thanks.
