the guy here in welly is awsome his name is DENISE from DENMAK motors, i asked him bout my V8 conversion into the RX7 and he asked me if it was disk brake rear, i said yes he said sweet you'll be fine
the only things he is going to check is - throttle return springs on carbie (2 of them), make sure the firewall is sealed, driveshaft is balanced, the build quality of my mounts i made (just need to do test weld in front of him) and thats it
all that for $350 but im gonna get my reclining race seats certed anyway even tho the original rails bolted to them and the floor
:D
there is more than one certifier in aux too.
welly has around 5 of them and i know aux is nearly double that.
