epoxy124

The 131 box is a good change with a slightly longer 5th, feels a bit more truck like compared to a 4 speed or 124 5 speed though. Like the axe work on the tunnel! I did it with a welder.  Had to use a fairly large hammer to make room for the filler plug, and the top of the bellhousing. Also needed to move the handbrake back a little to fit with the longer lever extension, but not too dificult.

Funny, Ive got a spare 1608 that had aluminium washers under the water pump pulley to space it out a bit- seems like fiat made pulley offsets different depending on the phase of the moon at the time..

The back has the standard steel spacer plates on, and the front doesnt - the brake disc hats are a bit thicker than the originals, pretty much exactly the same as the original + factory spacer. :)   I put them on before lowering the car and it did look a bit like a square roller skate.  I'd like to try something like a 15x7 Rota Shakotan but $$$

Hi

 I've got a 125 with some US CD66 replica wheels that have been on for a couple of years.   https://autoricambi.us/cd-66-style-wheels-15-x-7-set-of-4/  They are 15x7 and 23 offset. Fit perfectly, very snug at the rear which is just how I like it, no rubbing but wouldnt want to be any wider track there.  No issues at the front either. With 205/50 15's the steering etc is very similar to the 185/70 13's that were originally on it prior to mods, of course the suspension is lower, stiffer etc now so apples to oranges. The track width is a bit wider but wheel centrelines not much different to original, maybe a cm or two wider.
