when i got the windshelds,(4)years ago,he only had one set left.the angles were very hard to align.thats why they stoped making them.bown is sorta strange guy,other than what i paid for them,i brought them home on the palsn,since we were in californiathe shipping was moore than the air fair!maybe if there cracked,one thought is toremove them,reglass them to cover the cracks,and pait them black,plus the center with the guages.just thoughts.
