1990 Exciter

I was wondering if anyone out there knows this sled really well. I just bought a 1989 exciter for a parts sled. The belly pan on the 1990 is plastic. The belly pan on the 89 is aluminum and slightly different. I was hoping to use the metal pieces that the tie rods and stablizer bar goes through. But they are slightly different also.It also looks like there is not any difference in part numbers on the fiche. Was there a company that made aftermarket belly pans for them?? If so, who?? Neither one of the sleds have a widening kit on them, so I know thats not it. I know Bender made those.Any help would be great.
700 miles on this year so far!!!
