Looking into waggy axles..... are they all offset?
No. But centered ones are harder to find. Most are AMC 20s but single peice shafts pretty solid set up.
Waggys front mini truck rear. Need like 1" spacers to get em dead even. Waggys should be 59" toy 8" ifs rear is 58".
Could do a Isuzu/Honda rear 44 too those are 58 or 59 I think.
If you did a Toyota 8" front I'd do spacers and use an IFS rear axle which will get you to a 58" width.
IMO to keep it stock looking ish you need to stay under 60" wms to wms. Lots of ways to go about it.

(only way to clear 37s would require a bunch of cutting on these)
