Nice update(s). The replacement shocks and spring look nice and are quite straightforward to construct. Just make sure you treble-check the lengths, as sometimes they don't fit into the recess in the plastic as snuggly as you think. Also, I find it helps to makes twice as many coiled springs as I need. I then select the best examples. I find that it is a good practice to get into as it is difficult to get an even coil when done by hand.
Hope that helps,
Kind regards,
Bill
