I was doing a little thinking on this today.....
While I am tempted to just use the JK8 kit parts that come from the J8 to convert the vehicle forever, I have to wonder if that is the best choice in the long run? I think a 'final' conversion would be the best for me, but I just think its SOOOO much work overall....and cost. The door replacement method seems to be about the right balance in the long run. Here is a JK8 (ish) conversion I saw at EJS.
The rear doors access storage boxes between the wheel tubs and the seats. I don't know, creative concept, but I think its just a little bit too busy for me in this form. I think that same feeling would carry over to an 'insert door' style conversion?
Now this style of conversion....
The complete JK8 conversion with the factory 4-door sides removed just seems SO much cleaner and simpler in the end. I think I am so attracted to this style of conversion because what I really want is the long wheelbase J8 '3-door'.
In this style conversion the B-pillar from the factory 4-door JK body is eliminated and replaced with the same style as the short wheelbase 2-door.
On another note, the top, I did have an idea about making a jig for an aluminum top by making said jig out of a honeycomb errector set looking arrangement of laser or waterjet cut plates. The aluminum sides and top would then be cut to shape according to the modeling. The sheets would then be 'bent' over the jig structure to form the complex shape of the JK top. I think this would be about the best long term solution for making a top.
Anyways, just a few thoughts.
