Bootloader for 16f87/88 that doesn't use UART

[skimask]

I looked into using something like the 18F1320, but the HW UART pins have moved, which means a redesign of the PCB.

You using DIP or SOIC?
If DIP, put one in a socket, pop out some pins and run some jumpers.
Not the best fix in the world, but works for me.
If SOIC, maybe cut some traces and run some jumpers.
Same thing, not the best, but it works.
