Great work so far Brings back memories of my build (about 25 years ago) still got the old girl (car and wife lol) due for another rebuild/refresh I did all the same thingd you are doing and it was well worth it as there has been no rust returned in all that time. will be adding an RB30 this time around and rear disk brakes along with many other upgrades. so keep up the good work, and it does get easier as you get towards the end. if you can actually call it finished? as there is always something else to do, add, replace or upgrade
