Yes Jacques, you are correct about the battery frame rivited to the base. My base has lasted far better than the box too. It also need a slight 'tweak' to straighten, but has no major pitting that might be a hole. Having said that, it is often only after sandblasting that these things appear. With this piece I am quietly confident though.
I will copy your photo showing the fuel filter, if thats OK? Every bit helps.
Will need to get back to you regarding dimensions, but first thougts are that they are quite correct. I will confirm this later this week.
I fully understand the decision to make slight 'alterations' or improvements in restoration. I like to think some of the changes I make are what Ford would have done if they were able to take their time and pay more attention to quality in construction
P.S: You Chev guys, they aren't built any better, I have been reliably informed.
