Status: offline 		Thanks guys. I'm going with a spool for this one. I may eventually machine an actuall diff..
Yeah mudgy I did make a sheet metal one a few years ago.. It was made from 1/8" steel and weighed a ton and wasn't precise at all.. This one is very precise I have about 0.0003 tolerance and that's just because I got about 0.0001 backlash on X&Y I got backlash compensate dialed in in mach3 but I'm still out 0.0001 no biggie..

Status: offline 		Thanks.. Yeah this fabricated Rearend should make the Beretta look like its all business from the rear view.. That one you built looks pretty cool man.. The other one I built wasn't actually made from thin sheet metal. It was built from 1/8" steel,, I attached a few pics of both..

Status: offline 		I recently purchased some decent shocks for the Beretta. The shorter ones which I'll use on the rear are
Ready to be bolted on.. Once I get the Rearend done. The longer ones I'll use as struts on the front, I'm going to
Remove the lower spring and machine a sleeve that will secure the spindle and brake caliper mounting bracket.
