looking for some wiper arms & blades for my 75 914. also, when looking at rims are there any specifics to look for other than 15 x 7,8... 4 lug pattern. is there a brand name to look for that carries the size for a 914 or would any rim and wheel dealer carry this as a standard size and pattern? inlighten me please.

You want 4x130 lug pattern. Offset will make a difference depending on rim and tire width. There are not a lot of 7 and 8 inch options sadly, but a lot more in the 5.5 to 6 range. Mostly you will find either 914 specific wheels or old VW rims, with a scattering of aftermarket options available in between.

I think we have some wiper arms on the parts car. Lemme go check.
