Axle width on a '92 D21 Hardbody

[Jim Jans]

How wide is a rear axle from drum to drum on a 1992 D21 Hardbody 2WD truck?  I was told the ratio is 3.55 and I want to put it in an older MG car.

 

Thank you

I think maybe 60". I assume you don't want to narrow anything if you don't want to. Also does the MG have an LS or something in it? If no then there are lighter weight axles that are narrower below...

 

WMS to WMS below...

 

1200  51.50"

 

B210  51.75"

 

B310 (210)  53.25"

 

510 Wagon 53.5" H-190

 

S110 200SX  55.25" * The '81-'82 S110 was an H-190 same as the D21 2wd four cylinder.

 

710 55"

 

2000 Roadster  47.5" H-190

 

521 truck........... 52.5625" H-190

 

620 truck........... 53.5 to '77 

............................ 54.5 '78-'79 both H-190

 

720 truck .......... 57.5" H-190

 

 

TREAD WIDTH this is NOT WMS to WMS and more a function of rim offset if any.

 

L520/L521/PL521...... 49.9" H-190

PL620/HL620............. 50.4... 50.8 after Mar '73 H-190

720............................. 50.8 and 53.1 after Nov '82 H-190

2000 Roadster........... 47.2  H-190

1200........................... 49"  H-145?

B-210......................... 49" H-145... 49.02" '74 on H-150

B-310........................  51.2"  H-150

PL510 wagon............ 49.6"  H-190

610 wagon................. 52.4"  H-190 with L20B

710 wagon................. 52.3"  H-165

A10 wagon................. 52.4"  H-165

The MG has a 51" drum to drum and the weight is 2,403 lbs @ 68 HP   The D21 is 2,645 lbs and has 120 HP.

I'll have to check the brake slave cylinder bore and leaf spring distance.  The MG has a ratio of 4.55, I heard the truck has a ratio near 3.55?

My MG rims are 4x4.5 lug pattern, so an adapter would have to get the 6 lug rear end to a 5 lug rims to match the Dorman rims I have up front, 939-124 should work.  I don't need the bolt patter to match between the front and back, they have hub caps that cover the lugs.  They are 15" rims, but didn't the 4x4 trucks have 15" rims?

The B210 should have a 4 bolt pattern so my rims may fit that I already have on the stock MG rear end.  But getting a rear end from those older models might be like getting hens teeth?

I'll have to check out your list of other rear ends.

 

 

Thank you

Your location says , Hood river,,, is that Oregon??

if yes,  finding a b210 or B310  rear end shouldn't be that impossible within maybe a few hours drive at most. . 

 

 

 

[Jim Jans]

Yes, Thats Hood River, OR   Portland is about an hour west.

Forget truck axles with the 6 lug/toooo wide headache that comes with it. For 68 HP you can go with something from a B-210/210/1200 they are plenty strong.

 

Coil spring on MG?

[Jim Jans]

No, My MG is a four-door model (ZB Magnette) and they have leaf springs with socks, the leaf springs are about 38" apart from each other.  The drum-to-drum measurement is 51".  With a 4x4.5 bolt pattern.

 

 

Thank you

Datsuns are based on the British 4.5" but are referred to 114.3mm.

[Jim Jans]

That should make my job easier.

 

Thank you
