6.5kg.... they have awesome stuff . They can toolroom copy anything. There range of racing parts for vintage racers is just out of this world. Would recommend anyone just to down load and spend hours just looking thro it.

2000 is down there - am trying to hit 2100. Trying to get there with aluminum wheels and stock exhaust. That would leave me mag wheels and a lighter exhaust for an additional 70, but will need a boat load of money to get them.

Glad you enjoy it. Really excited to get the new rear back and assembled into the cradle. The half shafts were good for 11 lbs. Hope to get 20 out of the rear. Would put the rear assembly down around 240.

Kind of reminds me of racing bicycles. Saving a gram here & there to get that magic number. I bet you'll feel it in the spirited handling car. & I know you'll feel the difference the Webers make! Even before I began jetting mine I could feel the difference.

Yea - I am really getting excited. I will weigh it again once the rear is back in. I have a feeling it is going to be close to 289 weight. I geared it with 3.73. That puts the top of 4th around 148 at 7k and a 700 rpm drop into 5th - still above 350 lbs trq.
God I hope I can drive it
Looks like I got 12 out of the half shafts.

These are the heavy duty output shafts from Crosthwaite & Gardiner. They run them in race cars including Cobras. The Outer housings are aluminum.
Still 19 spline -
Stock weighs 8.2

I think Grubby (John) sold one out of his ERA 3 or 4 years ago and installed the ERA rear. I don't know how to search the For Sale forum but you might PM him and see if he will tell you what he got for it.

DanEC and ERA2076,
I did sell an ERA rear about 4 years ago. It was really hard to sell. Likely due to the very limited number of new ERAs each year.
It only had 800 miles and looked new. It finally sold for about $1500, complete - less the 6 pin hubs. A pair of rear six pin hubs is roughly $1000 from ERA. So the net was about $2500. My memory may be slightly off, but I remember thinking the buyer got a steal.

Thanks Grubby -
I hear you on the value, but want to price it realistically. I would rather someone have it, than store it. Your net is about where I thought it would be with shocks.
