I'd like to know if the others were Liska or OEM. If OEM it was a good idea to replace them. If all are new now you can ride knowing what is going on between your legs and RIDE THE PISS OUT OF IT
with the confidence of a job well done.
As for the gaiters if they will fit tightly on the lowers without the dust boots and you've made a couple spacers with pieces of large hose they should look good with hose clamps at the top and work as intended.
