[Roadsters] question on power to the rear end

[Mark Sedlack]

I've got a Ford 8.8 LSD axle in our '66 with a 4.3 Chevy V6 engine that's 
mildly built (approx 250HP). A 9" would be overkill and a bunch of extra, 
uneeded weight IMHO.

There's a printable sketch on my website that has all the dimensions I gave 
to a reputed local shop to rework a stock Mustang housing so it would bolt 
right in to the Roadster.

I cut off all the mustang mounting brackets and did some grinding to give 
him a smooth housing to cut down.   He did the narrowing, added new perches, 
and set up the 3:73 ring & pinion for around $700 IIRC.  The used axle I got 
for somewhere around $100.

Direct to the page on the axle is 5-18-03 Axle, Engine,Tranny
Or you can go to the main page and use the links in the left frame to peruse 
to whole project.

I had Moser shorten and respline my stock  Mustang axles.  I also had them 
redrill for the lug bolt pattern, and press in new studs for $200 or so.

So I've got about $1000 in Ford 8.8LSD with all new bearing, clutches, truck 
S-spring, etc. with me doing some of the grunt work.
