In the beginning of this site the say me abarth did nothing with the 127 .Litle by litle whe find out that it was not like this and the where working very hard in some country like Belguim,Spain and Italy for promoting this car that have the same engine like the A112 in some country .See the photos and you will marh up that the intake for oil is on the other side than after in production A112 .Also in the detail design you see that abarth was working with the CD 30 wheels and not with the smaller so that you have to fit the gr2 wings .And so on :

here you see also(it was in 1972) that on the same time abarth works on 124/A112/127 cars and use same parts

I find one of the first leaflets of the A112 and here it is (ps  not only the car is nice !!)

my muffler is sligtly diferent (the tail pipes exit in the rear of the muffler as oposed to comming out in the middle :)

see also that the oilintake is on other side than the later A112 engines .Than you now also that on a 58 abarth must be this type of intake/valvecover
