hey mate welcome,well done for choosing a 1200.i would say(not 100% but)that standard 1200 blocks would fit,you can get them from your local AUTO ONE they are the only one that list them round my area anyway,reseting the rears springs are a better way to go but if you can find someone to do a resonable price.i pay 100 bucks.some want 400 pfft.i think cutting springs is fine but is touchy subject some people will tell you not to,if done properly its all good.if you get a photo up we could confirm
