If your looking for door seals, Soffseal
) is already making a line of Monza and Vega Door
seals. The set from them is $75 I believe. But, I got
mine off ebay from someone selling a number of them at
$54.00 for the pair. Go to ebay.com and search for Item
# 1813238816 - "75-80 Chevrolet Monza door seals".
Good price and I've heard good things from fellow
members about their product.
