Chris: I don't have any test data but it should be easy to obtain force data for this energy absorber. I will be interested in any data you might discover if nobody can provide the Delta-V data you seek. The force data can be obtained by getting an exemplar energy absorber (from another 87 Dodge Aries at a wrecking yard or new from a Chrysler parts department) and having it compressed at a local mechanical test lab. When tested, have the lab measure the compression force as a function of displacement. Knowing the force v. displacement data and the weight of your accident vehicle, you can determine the g-force and Delta-V of the vehicle mathematically. If you're not familiar with the mathematics, I'll be happy to help you after you obtain the force v. displacement data.
