I assume I will be spending a fair amount of money on restoring my ’83 DeLorean over time, so where possible I like to save money by doing as much as possible myself. I usually enjoy doing it, and if it does not work out I can always choose to spend the money at a later date. Since my car only had one door strap upon purchase, and that one was pretty worn, I decided to make my own new ones. Had the car had both straps I probably would not have bothered. You can get new ones, both black and grey, in both the earlier style with a metal ring where you looped them through the door handle, and the later ones that are actually attached inside the door, from Delorean Motor Company, but instead spending $70 for the pair, I spent just over $10 on material. But note that original ones are, as far as i know, real leather, around a webbing core, the ones I made are all vinyl.
20 x 140 cm of grey vinyl, which actually was more then enough for 4 straps, but I only needed two.
1 spool of heavy duty synthetic off white thread to match the original
1 tube of contact adhesive
And here is one strap fitted to a cleaned and refurbished lower door panel.
