Hi Guys
Can anyone confirm the measurements of the rear axle housing, from LH wheel mounting flange to center of pinion and RH wheel mounting flange to center of pinion or
the center of the LH spring mount to center of pinion and center of the RH spring mount to the center of the pinion
I have a knock off housing changed to bolt on
Thank you

I have a stock MGA wire wheel rear axle sitting on my work bench. (I've recently installed a hybrid rear axle for bolt-on wheels.) Are you seeking measurements of the wire wheel axle? I could give you measurements of the hybrid axle but it is not 'stock'.

Here's the original (MGA) wire wheel axle measurements. From outer face of brake drum to the center of the differential (not the pinion gear) it is 25" on the right side, 24.5" on the left.

The hybrid axle is a banjo axle with the outer hubs of a Salisbury grafted on. This allows use of the stronger Salisbury axle shafts with the easier to swap differential (and lighter casing) of the banjo axle. I'll try to get the measurements later today.

These measurements may be off a little - the wheels are installed so I was trying estimate the position of the mounting area.

My hybrid axle:
Right side - 25 3/4" to center of differential
Left side 25 1/2" to center of differential. I could be off +1/8" as the exhaust pipe is in the way a little bit.

With 15x6" wheels +24mm offset, the track (center of tire to center of tire) is 48 1/2".
