Landwomble's guide to replacing shift boots and turret oil for Mk1

Thanks for the guide!
I’m going to do this tomorrow but didn’t know about the nylon bush on the end of the gear lever? Would a Halfirds or car parts place stock these so that I can still do this tomorrow?
Also where could I get some more heat/sound insulation from?
Thanks again for the guide I’ll try and take some picks and get them on next week.
