Non the less.. You are doing a great job! seems you kinda got the most sought parts already.

Thanks, I'm doing my best and learning along the way.

It turns out my motor is not sitting where I need it to be. The valve cover is pretty damn close to hitting the hood and so is the front velocity stack. I'm also far from being able to get a good angle between the transmission and the diff. The motor needs to be lowered a bit. The 620 mounts are too high. I ordered some cheap Rockauto 510 mounts but it turns out its the same thickness as the 620 mounts........ about 10 to 12 millimeter thicker than my original mounts. So that's not going to work...

I have a pair of old 510 mounts which are the right height that I'll try to see if it works, according to Baz it should. Trying to find a brand new set ain't easy though...

Anyway, on a positive note I'll have my custom headers and exhaust made this fall by a shop.
And we finally got personalized licence plates in Quebec since July 27. I tried to get DATSUN but it obviously didn't work... So i got this instead

Good you are working on that critical detail. Any shortcuts or compromises in that department will lead to vibration issues and a miserable driving experience. Well worth sorting out properly the first time whatever it takes

As you said, I think it's a critical detail if I want it to run smoothly.

Here are some pictures to illustrate my issue.

Rockauto 510 mounts VS OEM mounts

Transmission position. I'll adjust it and make a shim when I get the right motor mounts, but I think it should be close to this. Maybe even a little higher.

Clearance issues with the hood

Looks like a nice project. When I cut the tranny tunnel for my KA box, I did it nice and tight like yours, I ultimately had to open it up more due to an awful vibration it made against the tunnel at low rpms.
