just bought a golf yesterday its an 87 8v gti digifant and i have some problems with it. im pretty sure it needs a new heater matrix which i have ordered off ebay btu i have no idea how to fit it! i know the centre console has to come out and the bottom of the dash but as far as it goes im a bit lost beyond that. help!!

then the next problem, when i put my foot down it hesitates and has no guts at all in any gear, now i had a digifant before and i know they pull like trains.
will it be down to my cooling system problem? i put new leads and plugs on it today but not a dizzy cap and this has made no difference at all.
i will chance the dizzy cap at some point, but will this cure it? im stuck for ideas please help!!!
