since production vanished,used prices are now more than original new.maybe koleno will retool and start production again.hopefully on a diet too.i dont think dart has any interest.somebody needs to fill the market with something respectable and affordable.those companys know there is a desperate need.not that it matters,but, i sent an inquiry to dart asking about possible wedge and hemi blocks.if i get a response i will forward it.i need another block also..cross your fingers...
