Steve, The reason I wound up designing an alternator for the De Lorean was because of Pep Boy's. You get what you pay for. I have gone thru more batteries, starters and alternators for my family of cars, not just De Loreans but others to. They rebuild with checked out used parts and don't replace with new parts as we do. My design for the De Lorean 140 amp alternator is warranted for life $195.00 exchange. Yes were not around the block unless you in Dallas, Tx. but UPS is 2-4 days. I just sent some small parts to Belfast, Ireland for about $6.50 postage and arrived in less than 6 day's. Window motors, If you can't find new ones that fit your budget, then maby I can fix the old ones. John 11004
