Adam - The washers are in the kit for "grip length adjustment" purposes. The length of the bolts was set to minimize the number of threads in the sleeve (either the trailing arm or bushing sleeve). It's not a good design practice to have "threads in bearing". For cars that have only one alignment shim, the bolt may be a little long, and requires two flat washers to ensure that the nut doesn't bottom out on the shank of the bolt. If more than one alignment shim is used, you should use only one washer under the nut. The washers are a very snug fit on the bolt shank, but they should fit. You may have to "walk" it on a little. The washers are sized for SAE 7/16" threads, while the shank of the bolt is a metric diameter that is larger than 7/16". There is no requirement for an additional washer under the head of the bolt. These washers are not in the official DeLorean Parts Manual. Keep in mind that you still need to use all of the large flat washers that are in the stock joint, although you may want to flip the washers over if you find a deep wear groove in them where the sleeve has been bearing on the washers. The large flat washers must go back in in the same order as they came out. Of course, the shims must also go in the same as they came out to preserve the alignment of the rear wheels. Please feel free to ask any further questions that you may have.
