hello david!
I believe the first one available is for the j-70 as far as pages and exploded type diagrams go. the j-65 is very similar with the biggest differences being in the gear case. the j-25 is even more closely like the j-65. someone out there may have the j-25 parts catalog and though it won’t have exploded diagrams, it may help. I used to have a catalog for the j-70 but I gave it away before I was smart enough to scan it. 🙁
are you the david who had a crestliner voyager and an alumacraft flying C or D? if so, I will have a few questions for you. I just got a flying C the other day with no upholstery. please let me know at sabraaten@hotmail.com
thanks!
scott
