Spacers arrived, it's all back together now.. thanks for the info guys. .
Tyres are fubar now though (only noticed when I filled them with air :roll: )
Good news is, the wife really likes the Aggressor (no exactly retro, think it's an '07) but it only owes me £50 all-in so I don't care (the Marin and (arriving soon) VooDoo fill the retro requirements
