IT IS DONE!
Finished it off this morning instead of going in for a few lectures. The boot I ended up using was a Repco boot kit part number 100-017 . It wasnt a perfect fit but its pretty dam good and only cost me $12.00, compared to the $70 nissan wanted. Ive taken it for a drive and have done full lock circles each way and theirs no obscure sounds or anything. Am yet to look under neat to see how the boot looks and if its weeping at all haha, will give it a few 100 k's and ill suss it out.
My advice; Pay someone to do it.....
