AC Subframe Fitment Issues

<< < (2/2)

sandblaster:
91-04 will all interchange, I suspect that 89-90 will also although they use different part numbers, 87 has it's own part number as well as 86.
85 and older have the sub frame as part of the frame.

just to be certain, you are talking about a 500. if so very little changes over the years. I have used several AC subframes and have had good luck. maybe they sent him one for something other than a 500. subframe should be the same from 89 on and maybe you could use a 89 250 as well

I just ordered an AC Subframe and they did a HORRIBLE job on it. It's the correct part number, but the main area of issue was the cross bar that  doubles as the airbox-rear fender mount point. It was welded 1/8th inch to HIGH on one side, rendering the lineup of the other 2 air box holes off by the same distance. Further, the pressed in threads, where all hammered in at an angle, very sloppy.
The exhaust hole was drilled a few times, creating an oval.  Seems like the person who mocked this up, and welded it was drunk and did not give a CRAP about accuracy, detail  and worksmanship. I sent the sub frame back for refund.
