I have just purchased a 727 equipped with a Griner transbrake valve body.I need to replace this valve body with a manual valve body to be legal to race in nostalgia super stock class.I have been unsuccessful trying to find any installation instructions or modifications required for the Griner installation that may have to be corrected to use the manual valve body.I would really appreciate any information anyone has concerning this changeover.

I have built a few nss cars with trans brake. You just have to have the button disconnected. To activate reverse you just use the three prong nuetral switch. Run power to one of the outer two prongs and the other to trans brake stud.
