Caddy 5 speed gearbox identification hellllppp 😅

Hey,
just finishing off restoring my mk1 caddy and it's got a 5 speed gearbox fitted (yay)
now from a lot of googling and the forum coming up a few times i thought i'd join :-)

now the gearbox works great but R 1 3 5 are comically far away from the driver (towards the dash) and hoping to either get or modify the linkage to have a shorter shift/ make it feel abit tighter
and i'm wondering how to identify which gearbox i've got and which linkages would work with my setup
are there any pictures i can take to help? 🤷🏼‍♂️ 

Lots of info on the 020 gearbox and how to identify yours as there should be a code on the gearbox underneath it.

020 GEAR RATIOS

Buy a short shifter kit like Missinglinks.com Takes the slop out, then add a weighted billet and you have a move positive feel, and fifth gear isn't in the middle of your thigh.
