Looking for part numbers for turbo

[NorthEastJBD]

I have a twin turbo hook up that was purchased through Grady in 90's. Manufacturer was "Turbo Manifold Co." in Wheatley Hieghts, NY. (Picture of cover sheet attached)

I do not have the original bill of materials.

Does anyone know the manufacturer & part # of the turbos they used?

Any help you could provide would be appreciated.
