Well,here comes the disclaimer:It depends on who's doing the work,how the parts availability is working out in these daft times,and exactly how far you want to go. I know that's not much help,but I don't lie to Folks! In Texas,you shouldn't encounter surprise corrosion damage issues like we do. Up here,in "Salt&Brine Land",it really complicates everything. As a Ballpark,I'm with Rlaf75 and figure you can start the war easily at $1500,and if she's really in a poor state,the Cash Cow could conceivably Moo you all the way up to $2500. Again,this is with someone doing the work instead of you. Crack Da' Code by finding someone to trust,and have them do a deep dive into it to get you an accurate estimate. Good Luck,and please keep us in Da' Loop regarding the Whopper!
