I'm looking to find the stock axel width on a 55 first series 3100. I have seen a few different measurements floating around but nothing to definitive. I measured about 62" from middle of one tire to middle of the other.

I have an opportunity to buy a ford 9" that measures 58" from backing plate to backing plate and I'm wondering if the difference can be offset with spacers or anything like that, or if I should pass on a great deal and find one a little wider.

Any help would be greatly appreciated

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.

Most consistent way to measure rear ends(trucks and cars, that is) is from wheel mounting surface to wheel mounting surface; wheels and tires vary all over.

'37 GMC T-18 w/ DD 4-53T, RTO-610, 6231 aux., '95 GMC running gear, full disc brakes, power steering, 22.5 wheels and tires.
'47 GMC 1 ton w/ 302, NP-540, 4wd, full width Blazer front axle.
'54 GMC 630 w/ 503 gasser, 5 speed, ex fire truck, shortened WB 4', install 8' bed.
'55 GMC 370 w/270, 420 4 speed, grain, dump bed truck from ND. Works OK.

Can't find axle housing length.
But here is left and right axle shaft OL overall length.
51-57 1/2 ton, left.....29 5/8"
51-57 1/2 ton, right...30 5/8"
..........................+60 1/4"
Source 1929 - 1957 Chevrolet Master Parts & Accessories Catalog Group number 5.420

Looks like all 1951-57 1/2 ton axle housings were the same length. They all used the same length axle shafts.
