I also want to see a bolt-in cabin air filter. A legit HEPA filter is not necessary (Real HEPA filtration is usually expensive), for a lot of us a simple dust filter would probably suffice, but a pleated filter would be preferable over filter foam.
Edit: maybe real HEPA filtration is not as expensive as I thought (these are less than $10 USD per filter):

But HEPA filtration may be get clogged too soon. [/QOUTE]
I'm well down this path. HEPA can grow mold because it WILL get wet. HEPA is designed to eliminate mold and fungal spores but in a DRY environment. Put it in a wet/humnid environment and you lose the benefit of having a HEPA filter. But it can be cleaned. But the cleaning involves removing the cowl. And to remove the cowl you need to remove the wiper arms.
D. a way to relocate the windshield washer bottle to the inside of either front fender (I already removed the power antenna on the passenger side). Washer bottle relocation is commonly dealt with when going to dual batteries using the factory battery trays. With the washer bottle hidden, that gives us more space for items we need to access much more often. New vehicles often have the filler cap accessible but the bottle is buried, I wish there was a kit to do the same thing for an 80. I wouldn't mind removing the fender to install it, I need the space. I know a different bottle would be necessary, but I hope it could be engineered to use the factory pump.
Pretty sure Delta VS has these already.
