cieranc Posted September 3, 2010 Share Posted September 3, 2010 Hi all, I'm wondering if a diff from a Manta B will fit into an A series casing. I've been looking for a complete A series axle for some months, but to no avail. doveyte2800 has put me onto one, but it's missing the diff. Everything else is complete though. So, I'm guessing an A series diff would be just as scarce as the axle itself, so would a B/C series diff fit? Quote Link to comment Share on other sites More sharing options...
Shug Posted September 3, 2010 Share Posted September 3, 2010 Someone else will hopefully confirm, but I'm confident they will. I've been told the quaife atb diff will fit both so I guess the standard will as well. That is only if the A series axle is off a later 1.6 or 1.9. The earlier 1.6 and 1.2/1.3 axle was smaller.

cieranc Posted September 3, 2010 Author Share Posted September 3, 2010 (edited) Thanks Shug, any way of telling the earlier/later types apart? I've been looking for an A series axle for months, to no avail. Now I've tracked one down, all complete, but it's missing the diff. The guy's after £150 for it, is that silly money?

Shug Posted September 3, 2010 Share Posted September 3, 2010 They really don't pop up that often so hard to put a price on. Seen em go for 500 quid before, and also 30 quid! Not sure if theres an obvious way of knowing difference. The bearings are smaller on the 1.2/1.3/1.6N Quote Link to comment Share on other sites More sharing options...
rutts Posted September 3, 2010 Share Posted September 3, 2010 the axle on the 1.2/1.6 is smaller same as chevette 1256 axle, 1.6/1.9 is large like a b series. if you get an a series big casing you can fit the piazza turbo lsd diff and drive shafts in to the a series big casing. also b series is a straight fit. get a 1.8 ratio as it is same as 1.6/1.9 ratio. hope thi helps Quote Link to comment Share on other sites More sharing options...
cieranc Posted September 3, 2010 Author Share Posted September 3, 2010 Thanks gents, think I know what I'm looking for now. The Piazza LSD's seem to be more rare than the A series axes though! Quote Link to comment Share on other sites More sharing options...
bhp Posted September 4, 2010 Share Posted September 4, 2010 Thanks gents, think I know what I'm looking for now. The Piazza LSD's seem to be more rare than the A series axes though! Hi cieranc, Why do you need an A series axel? & why are you looking for an LSD? What axel have you got & what manta are you going to fit it to? Sorry for all the questions, but i've tried most combinations & maybe able to help you with yours! All the best, bhp.... Quote Link to comment Share on other sites More sharing options...

This helps Rutts, cheers, but raises more questions! When you say smaller, do you mean less beefy or narrower? I was led to believe all A series axle casings were the same width (55"), and the B/C series were 1" wider? Hi cieranc, Why do you need an A series axel? & why are you looking for an LSD?

Hi Bhp, I'm rebuilding a Chevette to a show standard, and am running a Ford Puma 1.7 engine with type 9 gearbox. I've been working on this project for months and until recently never gave the axle a second thought. I joined one of the Chevette forums not long ago and quickly learnt that the stock shove-it axle/torque tube is simply not up to the job. An A series axle is the recommended solution as it's just 1" wider than the stock axle, but the B/C axle is too wide unless arch extensions are fitted. As I'm keeping it looking as standard looking as possible, arch extensions are definately out of the question! Also, I understand the spring seats are in the same place on the A series and Chevette, whereas the B/C has them further apart than the Chev. So really the A series axle seems the best all round solution. I'm not looking for an LSD, it was just mentioned that the Piazza Turbo axle would have one. I've ruled out 4/5 linking any other axle, as I want to keep the original back seats so don't want the link boxes protruding through. At the moment I have no axle, just the standard Chevette axle, but have sourced an A series axle complete, but missing the diff, and a couple of complete B series axles (1.8 and 2.0). So my plan was to use the A series casing and halfshafts, B series diff and backplates/drums (bigger) and steel torque tube (Chev has ally torque tube, known to be weak). Good Plan? Or Seriously Flawed plan? EDIT: I've just noticed Rayman's thread here on a similar subject. Info between these threads seems to conflict?

rutts Posted September 5, 2010 Share Posted September 5, 2010 (edited) the manta a 1.2/1.6 small casing is what you have on a stanard chevette 1256cc motor. the 1.6/1.9 has the same width but bigger diff housing like the b series so the 1.8 diff will go in nicely put the pinion gear and diff with crown wheel in the a series axle casing you can get dovet2800 providing its the large diff casing he can advise you. if you buy a standard piazza axle (non LSD cheap) you can fit the top links down to bottom link making a triangle weld them together connect your panard rod and you have a five made into three link that works a treat with discs on the back and you dont loose back seat easy peasy.
