We are in need of six new pivot blocks for the corner block pins . I think our corner block pins are in good condition wasn't sure if there should be spikes at the top or if we are missing a part could you please look at photos and give us an opinion. Might as well throw in six plastic roll glides as well. Thank you for your time.
