WANTED: WANTED: IRS Dana 44 from 1985-1996 Corvette C4 Manual Trans in Cobble Hill, British Columbia for sale

I am looking for a Dana 44 for my Kit Car project as the Dana 36 I currently have won't handle the power I will be putting into it.
Ratio can be whatever, I will replace Ring and Pinion as needed.
I only really need the Differential itself, drive shaft and stub axles are not needed but would take them if its a package deal.
Would also consider a whole parts Car depending on price, location, and condition.
As stated in the title, these rear ends were mostly found in '85 - '96 Corvette C4's with the manual transmission.
Not interested in Dana 44's from '80-'82 Corvette C3's and Vipers.
Not interested in Steel Dana 44's.
Not interested in other Dana 36's, UNLESS its a aftermarket one able to handle 500-600hp at the crank.
Example:

See pics for samples / differences between the 36 and 44.
Dana 36 has 8 Bolts for the diff cover, the 44 has 7.
