Viper T56 to lsx 1967 Firebird questions

[im4u2nvss]

I have a Viper T56 for my 67 Firebird project. The main reason I wanted the Viper T56 was for the forward shifter location. I will be installing a 98-02 ls1 camaro front plate, input, bellhousing to mount it up. My questions- Is the mount in the same location as GM T56? Will GM style T56 tranny mount bolt to Viper case? Also, has anyone found a good way to get a speed signal to work with say, a AutoMeter speedo? I could always use the GPS signal box from autometer but would like to find a way to use a sensor on the tranny. Thanks to anyone who can help me!
