Valance is there - painted red by PO. Wipers switched? I never noticed, but I never drive in the rain - not for 18 years I've owned this TR. I'll change them over if they seem to wipe more surface that way. Finally, I'll check the grille for attachment points. I didn't find any the few times I looked. The car looked just the way it does now when I bought it but it had no wipers, a cooked alternator due to installing the battery backwards, a worn top, no windshield washer, and many electrical shorts. I did all the correction work myself, added a stainless steel exhaust system(by a local shop, not me), new brake lines, new window regulator and door check,new top (not installed by me), new alternator, tube shock conversion, rebuilt differential.. It wasn't running when I bought it - I had to tow it home with a rope and did the work in my garage where it still sits while my Honda sits outside, exposed to the elements. It's on its second battery and second set of brake pads.
