yea like waggy said above...
'The DC5S seats are actually welded/rivoted to the rails'

i've been looking into this for a while now and have never been able to find a fix for the seats sitting so high...

Waggy... were you reading the thread where the seats were put into a da and the guy literally smashed the rails with a hammer to sit them lower?
i think ima try this when i get some time... cause im from newcastle and have no idea where or who would look into a job like this for me...
