Just to say, it looks as if the machines are positioned to be touching each other? That's not a good idea. Bits of vibration during operation can cause abrasion of the finish. It happened to our 1976 Whirlpool pair over a period of years.
I’ll have a pair of Maytags like that eventually one day but will have to obtain all the parts to convert my 306 into and 806 dryer. Most difficult thing will be to find an 808 control panel along with the fluorescent ballasts for the back lit panel.
