IRS gearbox and bits that fit?

Ok, starting to get a collection of bits to get my 59/67/68 jigsaw together.

I now have a type 3 late IRS gearbox, looks like it siezed on the input shaft so will be having a look inside it soon.
Is there any parts I can use out of my 67 swinger box that will fit the later IRS?

Is the selector and mount the same between a swinger and a IRS? What is the main difference between a type1 and 3 IRS box?

Bump,

Dangerous......

basically type 3 and type 1 are the same, the type 3 has the grub screw for the shift coupling on the bottom not the top, ratios depend on what model exactly that you're talking about, nose and front mount sections are interchangeable, some swinger bits are favourable, details will need to come from someone more g/box savvy.
