I forgot to share that recently the prices of the Dobinsons leaf springs for the front and rear of the FJ55 went down in price significantly (almost by half). Dobinsons made a whole bunch of them in bulk, reducing the cost, as opposed to making just a handful at a time.
The full kit starting price was over $4k, but now the starting price is $2770, depending on options chosen.
