20 years that how long mine have lived before they started cracking and flaking. im going to try to patch them maybe with some west system epoxie or marine tex but im sure ill have to buy a new set 3 or 400 bucks a block I think

If they are that expensive then a trip to an engineering shop or a joinery / woodworking shop depending on what you want to make the new blocks from
Might work out cheaper
