Jim Jans Posted May 29 Report Share Posted May 29 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 Jim Quote Link to comment
datzenmike Posted May 30 Report Share Posted May 30 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?

Jim Jans Posted May 30 Author Report Share Posted May 30 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 Jim Quote Link to comment
bananahamuck Posted May 30 Report Share Posted May 30 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. . Quote Link to comment
Jim Jans Posted May 30 Author Report Share Posted May 30 Yes, Thats Hood River, OR Portland is about an hour west. Jim Quote Link to comment
datzenmike Posted May 30 Report Share Posted May 30 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? 1 Quote Link to comment
Jim Jans Posted May 30 Author Report Share Posted May 30 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 Jim Quote Link to comment
datzenmike Posted May 30 Report Share Posted May 30 Datsuns are based on the British 4.5" but are referred to 114.3mm. Quote Link to comment
Jim Jans Posted May 30 Author Report Share Posted May 30 That should make my job easier. Thank you Jim Quote Link to comment
