Hello. First time poster. I have an older Ultrexx. I noticed one side of the latch bar broke off. I found online a replacement part. It looks fairly easy to replace. I also saw an option to get a stainless steel piece. Mine is a 60 in 80lb 24 volt model. R023MK00718. Took a while to find the serial number. Would the stainless work, or is it safer and easier on the unit to stick with the plastic piece. Thanks
