I got a 1961 dodge D-300 Power Wrecker.

it has a 360 2bbl,4spd.
but i'm not sure what gear's it has i was thinking they were 4.88 gear's like every other 60's 1 ton but this rig has 6.50-16's for tires and at 50mph it didn't seem to be revuing hard so i Kept it at 55mph.
truck stock had 8-17.5's as the 17.5's are still on the front axel but the rear wheel's have the 6.50-16's. witch i find odd that this engine wouldn't be screaming at 55mph if it still had the 4.88's.8-17.5's 30" tall and
6.50-16's are 28" tall. i wish i had a tach in this truck...
Cause i have a 62 GMC C-30 with 4.88 gear's and with it's 8-17.5's it would rev 3100rpm at 55mph, It now has 8-19.5's and it dose 67mph@3,100rpm. 8-19.5's=33"tall.

i'm trying to get new 6 lug daully rim's for it and run some 7.50-16's on it.
But i wanted to know if them new izuzu cab over's 6 lug dually wheel's will bolt on as mopar and mitso/izzy are so close on the newer stuff???
