Wiper Arm Assembly

Ordered new wiper arms from Allegro-Red Bay, Alabama. Removed and installed new ones. My old ones were cracked at the flange that bolts to the front of coach so had to replace complete assembly. The wiper was starting to wipe down past the windshield which no doubt caused the cracking.
Also found my motor bracket was not anchored down properly so had to secure it to the body of coach. Installed wipers correctly, tighten down all bolts and nuts. Back on line and working great.
I do appreciate this forum and all the concerned members for giving their advice/suggestions. Thanks to all !

Did you try utube search maybe information on chassis type vs motorhome type also Rome truck parts in Georgia they may have some inforemation Good luck
