help!! my B2 needs a frame

[kuivinenj]

I've owned my 89 B2 for 15 years and now it needs a frame do to rust. I've got a line and a frame from an 88 B2 that's in good condition but the guy selling it says its different from my 89. but searching around I haven't been able to find anything on what could be different. anyone have any info on this or have done a frame swap in the past? any help would be great thanks in advanced

The front of the frame rails are different. 84 thru 88 have a boxed end that the bumper bolts to. 89 & 90 are open ended and angle up. They have brackets that bolt the bumper to the frame. That’s the only difference I’ve come across on the frames.
