I recently replace my 3.89 diff with the 3.27 in my '70 GT6 with OD. I have
found this to be an excellent replacement. The 3.27 diff are much more readily
available. Often you can find a parts car at a very reasonable price.
The diffs in the later spits are essentially the same and will work with some
minor mods. but many of the later spits had 4.11 diffs.
If you change the ratio remember to change the spedo also.
Many of the other parts are cheap such as the roto-flex couplings and U-joints
replace them while you are changing the diff.
You should be able to find a junk yard diff for around $250, rebuilding will
depend on the extent of the damage, but could be as much as $800.
You may want to start applying penetrating oil to the bolts especially the long
bolt that holds the rear of the diff. You will probably destroy it getting it
out and even if you don't you should replace it. So order a new one up front.
When you are putting it back together grease the bolt to help you remove it next
year when decide to do the frame up restoration.

No, out of there. There's 2 ways you can supply the High-
Volume, Low- Pressure air:
1) A big compresser (5+ HP reccommended), with a very good air dryer, and a
special regulator.
2) Turbines provided by the gun manufacturer. They are about the size of a
welder, and pump a lot of air into a big hose at low pressure (HVLP). The
turbine action heats the air, which helps dry it out a lot (good), but
stays hot at the gun (bad, especially for lacquers)
> My question: how easy are is it to clean those things?
One of the main differences in most HVLP guns, is that they have
pressurized paint cups, rather than the vacuum in a siphon guns cup. An
Accu-Spray any how, of which the "cheaper" (yea, right) models have the cup
mounted under the spray head just like a siphon gun, don't appear much
worse to clean. (As you don't let your paint set up!) I have heard
complaints about some of the "conversion" HVLP systems (Binks, Devilbiss,
etc, which used converted siphon systems). Once you get into any system
with a remote paint pot, you're talking pain in the butt for cleanup.

Ain't that the truth!
Around these parts, most of the painters still swear by their siphon guns,
and probably will until California style regulations force them to change.
