I'm doing the same thing Frank and would be interesting to know. I seen a picture of a 45 with large buckets but I imagine you could use buckets out of a mid size or small car as there's not much room inside the cab. I'm thinking on trying to get a set out of an old chevette or somthing in that size. There are sure some nice new ones on the market but there sure expensive. Hope you find out as there are quite a few with buckets in the gallery. Bob T
