ERA will sell you a nice reverse angled shifter for the TKO. It looks great, and has the little fake reverse lockout T handle on it that is functional, but doesn't really do anything.
The TKO600 will fit in your tunnel quite nicely. Note in that picture there is a spacer between the transmission and bellhousing. If you choose not to use the spacer, then you must have a shorter input shaft installed on your transmission.
