Have a couple mk1 OE waterpump mounting housings. They have smaller hose connectors than mk2/3 styles. If you're keeping your mk1 original these are for you as they are NLA. none of the bolts are rusted or broken and they are not corroded. 20 each plus shipping, the smallest USPS flat rate box for these is 10.70, may go for a little less parcel post in a smaller box I dunno please email if interested:
