Nice to hear that you are cracking on with your build, nice one mate
Chassis is looking great
With regards your tank placement, I personally prefer the second photo of the tank, as when you come to fit your handbrake cables they run just above the diff & so there will be very little access if the tank was above the diff, just my twopence worth
It might just be the angle of the photos but parts D11 look slightly odd, they seem "too near vertical", did you cut the upper angle to 66 degree,s? hope you don,t mind me saying that, its just if the angle is wrong it might cause a prob later on for the up/down movement of the wishbones( be a bit close etc).
If its the photo angle i,ll crawl back under my stone
Nice work mate, you,ve really made swift progress
cheers
