A cheap shock to use for proper dimensions is the Gabriel Red Ryder Gas # 81478 73556 from Autozone. About $12.00. The Monroe Matic Plus # 32150 commonly referred to in parts interchange lists is incorrect. Although it will bolt up, the Monroe is too long when fully extended. The Delorean front suspension relies on the shock, when fully extended to limit the lower control arm downward travel. The Monroe will allow the lower control arm to impact the lower surface of the lower control arm pivot housing when the front of the car is jacked up, stressing and bending the sheet metal in this area. Not a good idea. Differences in the Gabrial shock from stock include the requirement to use spacers as usual, and the fact that the lower pivit bolt mount on the shock is 12mm instead of the stock 13mm (1/2 inch).Not a big deal.
