The 1/20 Tamiya kit provides full engine detail in contrast to the 1/24 version also available. Another difference between the two versions, is that the 1/20 kit also provides the decals for the 1978 version with red and white colour scheme (instead of blue) and so, I decided to build the 1978 version mainly because of the colour. One thing very difficult if you intend to detail such old kits is to find good references. So, I dived into my pile of old racing magazines and found a 1978 issue with a detailed development report of the car, containing several photos of car details.


I started with the chassis as proposed in the assembly instructions but changed the order more or less completely. First the front frame was completed as proposed in the instruction step 4 assembling all parts but the water reservoir.

Next, a plate scratch built using 0.3 mm plastic card was glued to the floor on the passenger side of the same shape as in front of the driver seat.

Then, the bar on top of the centre console (part A1) was glued in place followed by the chassis part for the rear axle (B30). This rear axle carrier was glue fixed instead of using the screw provided, to avoid the screw head. Due to some sink marks, the inside chassis sections beside the drive train tunnel rear end were scratch built again using 0.3 mm plastic card.

The meters on the centre console were partly removed during sanding, so, I decided to replace them with machined parts.
