That makes it necessary to slot the holes where the bumper brackets go through the body in the lower grille area. Over the years, many owners of R2 Stude Avantis have added reproduction R3 air boxes to their engines....and I don't think all these cars were 'shimmed' up at the front....I wonder what their secret is?

R3 Forward Posted July 26, 2019 Report Share Posted July 26, 2019 I am building a 63 and have installed an R3 engine All I had to do to make it fit with the air box and standard body shims is use smaller/shorter front motor mounts, but I also had to shave almost 1/4 inch off of the sealing edge of the top side of the air box.

mfg Posted August 4, 2019 Author Report Share Posted August 4, 2019 I like R3forward's idea of using the 'thin' front engine mounts and 'shaving' the R3 air box, hence keeping the Studebaker Avantis original 'nose down' rake. To me, as cool as the production line R3 Avantis are, they're loss of the 'Avanti Rake' has a negative impact on the 'look' of those cars.
