I can only agree with locklaw, but then again, I have my collector's and perfectionist hat on.
The chinese aftermarket parts are a good thing for people that just want to have a daily driver, take their rig off-road, want to do a restomod, just don't care about originality or are not prepared to spend 100K for a full 100% restoration.
I needed to have a rig for off-roading so I have tested a few of the juncheng parts (bonnet - doors) and we ordered a full body to fix onto my BJ40 chassis. Their design is nowhere near the original. Adaptations (cutting - welding) are required to make sure you can bolt the damned thing. Metal thickness is not the same as the original....Again, you get what you pay for... if you like to tinker and you have the capabilities to do so, then this is great...
I don't know about the US but there are a couple of companies in Europe that can do a perfect job to take your 40/42/43/46/45 tub and rebuild an entire new body. This will cost you 2X or 3X the chinese price. There are literally hundred of man hours to be spent on such a job, a lot of CAD work upfront to design the parts, molds to make, metal to lasercut and bend..... For the price, design will be 100% conform to original (all their design start from the original OEM part). Metal thickness is respected and sometimes increased...and they even make invisible improvements to reduce vibrations or metal deformations.....
To quote a famous French film dialogue writer : "le prix s'oublie, la qualité reste".
This is what is so cool about Landcruisers : classic car collectors and 4x4 petrol heads can share the same passion....
