Needing some help for model manufacture

[NothingAsFineAsaW9]

As i model in Ho scale 1/87.

I have been talking to wise model service who produces some decent  Ho resin/metal kits. 

Based off the IH 4200/4300 and the transtar 4070 coe.

Asked if they were/had any plans of making a single axle version of the above trucks. 

Was told they are very interested but need proper rear suspension photos of the spring ride (buckboard) suspension in order to consider doing these versions correctly or close to the real deal.

Hence where i need y'alls help i can't find any pics showing single screw 4200/4300 or transtar 4070 coe photos. 

PM me if you can help and I can provide the contact info for wise model service again this is Ho 1/87 scale. 

Thanks and any help is much appreciated
