I had the Monogram Ferrari 275 model repop since the 1990's. The last few years I acquired the NOS drop-arm chassis parts, Dynamic guide, a motor and Paul Gage tires. Put it all together and the guide sits on the front valance. I assembled the 1990's Mono Scarab from NOS parts but used the non drop arm chassis and it works fine with the Dynamic guide.
What does the Monogram guide look like so that it doesn't hit the valance or does the slot car not use the valance or is it cut out?
Thanks, Vince
