I just picked up my 83 Civic S yesterday from my local body shop. I bought this car 7-8 years ago in NJ with 50000 miles and a little rust in the usual spots (under rear bumper, behind one front fender). It has been in the barn since then, until this fall when I got enough time to pull the trim and interior off of it. I had some aftermarket patch panels that they used to fix the rust in the rear, plus a new RF fender from Honda. The car is now back in the barn - as soon as it warms up I'll start putting parts back on.
I've had the usual 1980's Honda parts success - I got 4 of the body side moldings from Vintage parts but no-one has the other two. Same for most of the emblems and rubber - about 50% success rate.
The only new problem is that the fuel filler pipe is bubbling in spots - anyone have a good used one?
