I know a lot of folks are still in need of Constructor parts to fix issues. I basically ended up getting in some extra to fix issue for my customers, and have some parts left. Right now, I can try to help folks out with parts for Burden, Unearth, Bulldozer, and Concrete. I can't guarantee I have what you need or how long it will last, but I will be glad to take a look and see what I can do to help you out at minimal cost. If you do need anything, please contact me through support.capturedprey.com to keep it all neat and tidy, and I'll check and get back to you within a couple days! If you include your zip or postal code (for the US or Canada) or your country for elsewhere, I can also get a shipping quote at the same time. I will need a description of your problem, and you can submit a couple pictures (1MB or less in size) as well so I can make sure I know exactly what you need.
