all sorted now
would like to say a big thanks to bernie for talking me through some possibilities earlier
also a big thanks to craig @ the place i cant rememer the name of

(cossymad's mechanic) for fixing it... and for cossymad for putting me intouch
it was the rubber gaiter around the gearstick getting stuck where the lift up reverse gate was, so you couldnt pull the gearlever far enuf back to engage properly

i'm SOOOO glad its sorted now as it was getting embarrasing having people help me pusht the car backwards
also got the quickshift on there now... its BRILLIANT!
