i own a nissan frontier, which i use for the delivery of goods for my small food business. i recently purchased some parts like the nissan tonneau cover (http://www.shopnisparts.com/nissan-tonneau-cover/) and throtttle body spacers (http://www.shopnisparts.com/nissan-throttle-body-spacer/) for more fuel economy. what else do you recommend for me to buy for maximize my frontier for my business?

Can anyone out there tell me where I can get window seals for the doors on a 1977 Datsun 620 pickup we are restoring. Csn't find them anywhere.

Dang... good luck with that.. I just finished my 85 Nissan 720 and when i ordered mine there were only 4 left in the country.. now only 2.. :)
but naw.. sorry tho... all i can say is hit as many junkyards with older cars as you can...
