it,s fairly simple all you need is a complete front end of an e34.cut e28 core support just about all the way out.place the e34 core support in place and trim as necessary.once all the lights and all are fitted weld core support in place(hood pin locks will remain in the same position never moving).then cut the e34 fenders and trim to fit over the e28 fenders and weld in place(the e28 fenders don't need to be cut if you trim the e34 pieces correctly).the hood will need very little trimming against the grille to match the contour.i suggest using the euro mtech bumper cover i think they compliment each other nicely.i know some of you are against doing such a thing to the e28 but for those who are for it, if i can be of assistance let me know.
