renix to 99+ intake

ok, in my quest to get more power out of my 90 4.0 i have come across onfo for a swap to a 99+ intake manifold. but the only thing is that they always talk about swaps from 91+ to 99+ intakes. is it possible to do this swap from a renix intake? dont know if they changed the intake manifold mating surface or anything like that throughout the years.

thanx in advance for any info you guys can give me
