We Had Brett's Hr in for a couple of oil leaks and a brake issue turns out there was a few more issues that we found!!! we ended up pulling the 6 litre out to have to fix the leaks found the power glide wasn't happy and had to modify the headers to suit the dip stick it was lacking pack the motor up to clear the xmember. but after that we sorted the brake issue set the pinon angle and put it all back in the hole looking and sounding a lot smoother another very nice local car and if your chasing any HR OR HD #holden parts give Brett a tingle The HR Guy 0407 115 679.
