Glad to have you back Grim. It's been since 2009! Sorry to hear about your truck being smashed, tho.

I see you have
posted in the Parts Wanted area of the Swap Meet for a trailing arm. Maybe that'll be a good start, in general. Also, maybe some Bolters here may know if RJ's family is still in the parts business. In the least someone may have some idea who else has parts that's near the Littleton area of Colorado.
Let us know how else we can help.
