UPDATE: Price dropped to $4250.
(03/12/2020) This shows that the DJ-3A windshield for the Koenig hardtop also will fit the Meyer CJ-5 hardtop (in this case it’s a CJ-5 half-top). To me this adds weight to my theory that the Koenig hardtop used on DJ-3As should fit CJ-5s. This jeep also has a DJ-3A body (cut side type) and grille, at the very least.

“1946 Jeep Willy.
A project my husband realized he has no time for. It runs and he does drive it around once in awhile.”
Since a CJ5 is wider than a DJ3, it would drop over the DJ, but a DJ Top width would not necessarily fit the CJ5 as you see this set up. Side fresh air heater vent in 46? I don’t think so.
