Trans linkage question

[csx452]

I'm going to swap a 360 into my 75 slant 6 Scamp using Schumacher mounts. I'll be using a 904 trans. What trans linkage will I need. I'm asuming the slant 6 linkage won't work.
Thanks for any info,
Frank

what engine are you installing?

I'm not sure of the exact year. I do know it is not a magnum block. It's one a friend built for his van and then decided to get rid of the van. I'll ask him tomorrow what year engine it is.
