I got a close look at the fiberglass work that Green Army Motorsports was doing when I visited them - it's really first rate. When they convert a Mahindra Bolero to a "JKU" there are a number of fiberglass parts involved - new hood, cowl section on the body to integrate the hood and a new windshield, new grille, new fenders and flares, hardtop, etc. It's really nice work. Fiberglass work is very labor intensive and labor intensive things can be done very well and cost-effectively in India.
The day after my visit to Green Army, Tushar (my designer friend) and the managing partner of the shop dropped by the house in Delhi to talk more. We talked about several designs I've done - the JL Grille for the JK and the JK Barn Door. This was an academic discussion since I have no plans to go into business to produce any of these parts, but products like those could be could be done in India cost effectively even after factoring in shipping to the U.S. and Green Army was offering to do it.
BTW Green Army does make a barn door for their Mahindra conversions, here's a photo of one. It looks like a liftgate, but the glass is attached to a barn door structure inside and the tailgate+glass opens in one piece as a barn door. Could be an interesting project for the JK - a structure that mounts to the factory JK tailgate and accepts the factory liftgate glass could be made to turn the factory parts into a barn door (this photo is from the article I linked to in the prior post).
After seeing their barn door I did some preliminary design work on a similar barn door for the JK which would mount the factory liftgate glass to the tailgate to create a one-piece barn door. I didn't take the design work any further because I've already got an excellent barn door as part of the Safari Cab hardtop, but it's definitely feasible.
Green Army Motorsports is just one of quite a few custom shops that do this kind of work, it seems to be a growing trend in India.
