Vega rb5 gen 2 spur cover

[pugboy]

I'm after a bit of advice. I want to run non-vega shell but need a spur cover. Have tried sandwiching extra motor plate and while it works it's not a great way round it and is a pain when you want to change motor or gearing etc. I know xtreme make a gear cover motor plate but on the site it says for the vega b4 only. If anyone can help that'd be great cheers.
