AE86 and 4A-GE measurements

[Sleepyman]

So m building a 1:4 scale AE86, based on Takumis '86 from Initial D first stage. Unfortunately the internet doesn't have all the measurements I need im looking for the following measurements: Width, Height, and Length of: the bottom of the block, top of the block, 16v head, bluetop headcover (guttering and camshaft-ridges would be good too please, ), rear axle, driveshaft, and T50 trans. There may be more but that's all I need for now, please and thank you :-)

Edit: the model im building is a 1983 Sprinter Truneo GT-APEX 3dr hatchback (I can't spell it, apologies), Zenki styling :-)
