First off, what's the size of the boost guage? 52mm? Also, if I decide to go with, say a new autometer lunar 30psi (or any new guage for that matter) can I just replace the guage itself, or do I have to also rerun all wires and vac lines? Any tips on a good brand/model 30psi guage would also greatly be appreciated. Btw, this forum ROCKS!!!!!!

 

If I were you I'd just get the Mopar 30PSI gauge, plenty around my parts have it and love it.
