Good timing.
I bought one of those back then and recently did the floor & tunnel padding & started to fit the rubber mat. It appears to be an exact duplicate in the embossed patterns & smooth spaces. There were two mats available when I ordered mine, one for the early Brazil model (basically a US '55) or the later Aero, with or without rear rubber, I ordered the early front only.
The tunnel area seems to be for a slightly bigger tunnel or is simply a loose fit, otherwise it's sized properly. I tried another layer of pad in various areas of my tunnel but after chasing the poor fit allover the place, I decided to let the upholsterer take a look. He agrees just the tunnel section is too big but thinks with some properly placed tunnel padding he can make it look good. He should do that about any day now.
Can't say if the mat is molded wrong, if I got the later version or if it would fit a '60 Brazilian model tunnel like a glove. Regardless, I think it looks good and can be made to fit about as good as the original without any glaringly obvious padding changes. If I ruin this one cutting the pedal holes, I'd order another.
I think the exchange rate was 2 Reals to the Dollar when I ordered mine, can't remember what I paid for shipping
