Lithgow LA101 trigger spring replacement instructions

Not long ago I traded two unwanted rimfires for one LA101. It was a zero cost deal and I was very happy with the rifle, with the exception of the trigger weight, which I measured at 3lbs 13oz... not far under the specification weight of 2.2kgs.
Curiously though, although slow squeezing the trigger was really bad, I found that just pulling straight through was quite reasonable. Like a military rifle, I guess. But it was never going to be a precision shooter like it was.
Nevertheless, I knew it was possible to lighten the trigger by replacing the trigger spring, so I ordered one from Gunbloke and much to my relief, it turned up today. In the meantime, I'd been searching high and low for instructions to prepare for the big day, but I couldn't find any. YouTube seemingly doesn't allow the demo-videos that I found incredibly helpful in years gone by, and even printed instructions were missing.
I can report that the instructions included with the spring are clear and easy to follow. And I can also report that the new trigger pull is light years better than the original weight.
I came across an outfit in the USA (LUMLEYS) that sells a kit with both trigger AND sear springs, but I'm happy with just the trigger spring upgrade.
As far as fitting difficulty goes, I thought the worst part was step 1, removing the waxy substance from the hole that covers the 3mm allen head bolt that holds the trigger group to the action! After that it was smooth sailing. You need small allen bolts though! 1.5mm is the smallest.
Care needs to be taken during reassembly when tapping in the trigger hinge pin, because it's steel and the trigger group is cast aluminium.
Sadly, when I tried to attach a photo of the instructions, no matter how much I cropped it, it was still too big! I thought I was going to be the only place to find them online.

mate, open the pic on your PC, see this example.
Under the arrow (click on the dots) and a drop down box will come up saying "resize image" and you just use the slider to get it under 700kb.
Then save as whatever you want to call it, then when attaching via the site, find it where you stashed it, click "full editor" then double click on the upload pic and "place inline" .
But first click on the page where you're printing first, where you want it to appear.
