Engine/Transmission (1994 - 1998) the ol transfer case questions

[AMendes]

i know you guys have seen this a million times i just cant find anything in the archives. 241 DHD upgraded to a 271. any obtions for a speedo relocater and how much of a pain is it to adapt the shifter on a 97 auto. i pull in CA so there are not any specifications on running OEM parts in the class, heck most of the pulls its just a "Diesel Pickup" class, if rules are set in place like i believe i want to be sure i dont apply the investment for nothing. are the classes back East regulated to only OEM parts and if so does the 271 even qualify under that rule.

thanks fellows albert
