Springs

[sprint]

Where is a good place in Auckland that i can get to swap some springs over? At a resonable price? Ive got a GZ20 soarer and it has cut springs and ive got a set of standard one to put back in. Ive tried myself but cant get the bumper thing back on the top of the shock with the spring compresses on, it wont fit! So can anyone recommend somewhere to do this or if anyone with tems on a Soarer/Supra that has done it b4 can offer any advice? Cheers
