Can the after market bumpers for 26/27 be put on a 25 with out a lot of grief?
Someone may know for sure, but the front brackets should bolt onto the frame if holes are present. At the most, you may have to drill a few holes. The rear brackets may be a different story, as the rear crossmember for 25 and earlier had a different crown than the 26-27. Once again, holes might have to be drilled.
I have 26 / 27 bumpers on my '23 touring. They fit but some holes needed to be drilled in the frame. I didn't install them on the car, but I kind of like them.
Make that 3 in a row.
I tried putting a bumper set on the 25. Front used all existing bolts...back was a different story. Had to add holes there.
