I just found your thread today and am glad you are back to writing! I drove a 69 JF40 through high school and half way through college. My dad has a 72 now. My wife drove a 71 her grandpa bough new and is still in my father-in-law's garage. Your long distance adventure in your 40 is great, but it raises a few questions for me:
Was the engine original or did you have some work done on it before you left?
What suspension and tire size do you have? It appears to be lifted a bit with 33" x 10.5"? It looks great.
Do you have an estimate on how fast you drove on average? My cruiser and the other two I get to drive are at home at 45-50 but much more and it is pretty loud. Just curious
Keep up the writing and pictures. I can't wait to see more of your cruiser in action!
