Default 1984 C4 installing a T400 Trans

My son & I picked up a 84 Vette w/ no engine & trans. We have put in a 350cu, 425HP stroker w/ T400 Trans. Does anyone know if a bracket is available to mount the 400 to the R700 bolt pattern on the torque tube? Do we have to fabricate it?
Any help would be great.
Thanks,
Project Vette in South FLA

..... I have a TH400 in my '87 ... a good friend who happens to be an aircraft certified welder and an awesome fabricator welded one up for me ... someone is making an adapter for the 4L80e but I'm not sure it'll fit the 400 bolt pattern ... there was one for sale on the forum recently ... otherwise , you'll need to fab one up ... the steel one on Grumpy's big block build is the way I'd go if I needed another one .....
