Got a friend with a 63 and a 64 Ferd 1/2 T p.u.s. Both appear to be same size pumkins. Does anyone know about what ratios might be in these and will their widths be comparable to the GMC? They would come with the springs, etc. Don't like the 5-lug but can deal with that. Also, what's a decent price? My present ratio is 4.56 and with a 327 it's all revs, really noisy and hot. Thanks h.
