Throw out bearing and starter problems

[UP THE RED VS]

So replaced my throw out bearing and after a quick 20 min drive it's rattling again, it's a bit quieter but still... Dunno what I did wrong but hahaha
Also changed starter motor and its grinding but I'll check the engagement tomorrow

Cheers

So I've got the starter off and can see that the teeth and been grinding against the flywheel, I'm wanting to remove that gearbox dust shield thing and put the starter back in and check its engagement with the flywheel.

Last weekend when I took the gear box out the dust shield came out fine but trying to remove it by itself is being a pain it's loose and I can wriggle it but dosent want to come out, any tips or do I need to undo the bellhousing bolts?
