I purchased a NAPCO installation guide for the AD NAPCO in 3/4 and 1 ton models. What surprised me is they use the stock leaf springs and make no relocation of them to a parallel configuration.
Doing research on non parallel leaf springs in trucks, it is quite common in 4x4. I have read where some said the springs had to be moved in parallel for the 4x4 conversion.
This not being the case as the installation guide shows, it seems if we could find a axle with correct width for the front of our one tons, and moved the spring perches, why could we not convert using modern axle, and transfer case and make a 4x4?
The installation guide shows the only holes to drill were for the mounting of the divorced transfer case. Can it be that simple??
