By your description it sounds like most of the hard stuff is already done? If I can gut a 69FB interior and make a decent driver look okay then anyone can do it.
I have been in your spot before. On June 13th 2003 I was in a near fatal motorcycle accident which changed my life drastically. I lost my job, wife, home, money, my dog died, my insurance was canceled, everything disappeared in less than six months.
It took me two years and two major surgeries to learn to walk again and I still fight the pain on a daily basis.
