I replaced the trunk spring bumpers 1 year ago. Found one of the bottom rubber caps missing. Replaced them with thick grommets at substantially lower cost then new bumpers on my 2001 gt. Hope this helps someone out .
No sorry. Tbh best bet is to go to your local hardware store and look for it in the plastic boxes most have or big box stores just have to look for them.
I recently came across a ebay listing that sells bushings for the trunk assist springs on all 2000'-2014' mustangs. I have been trying to find a cheaper option than having to buy the whole spring assemby ($35) These seem to be better than factory quality and fit amazing. I figured I'd share the link since these seem to be a common part that needs replacing:
These bumpers are designed to be a low cost solution for the rubber bumpers on all trunk springs in 2000-2014 mustangs. Ford does not provide a option to replace these bumpers other than purchasing a whole new spring.
