Diff Dilemna! Need opinions!

hey guys,
ive gotten myself into quite the pickle...after taking my car to the track and experiencing severe wheelhop and still running it (i know im an idiot...lets not go there) i have ran into more problems...the car only ran a 13.6 with a t5 5 speed, was planning on upgrading to a tko or 833 and building a 12 sec or faster motor for it next year (who knows if that will happen now)

the car has a 489 8-3/4 with 30 spline mosers and stock suregrip...well, the side with the wheelhop (driver side) axle has twisted splines...also, i found chunks of teeth in the rear end...the ring and pinion are fine, which leads me to believe it came from the spider gears (havent looked into yet, got late and have to work tommorow, but will check tommorow)
Im stuck as to what i should do...my car only runs 13's (with a stickshift albeit) and ive already twisted a tranny yolk (1350 too!) and twisted an axle...moser doesnt offer any warranty on these axles, so i have a few options

#1-try and find spider gears and try to get moser to send me one replacement axle...depending on how much this costs though, option two may be better
#2- get an axle and spool kit in 35 spline count, stuff it back into the 8-3/4 and continue to drive it (car is a street car though primarily, so not so sure how well the spool would fare...car gets LOTS of miles)
#3- forget the 8-3/4 altogether, cut the losses, and try and find a used dana in a-body length with what im looking for, or try to find a place that sells a complete D60 for 1200 bucks and under (i cant spend anymore...im broke)

What do you guys think i should do? the car is staying a stickshift forever, and my plans are only to go faster with it...it is also a street car before anything else
im scared though that whatever i do if i get wheelhop again i may break stuff again (was thinking of sticking twisted axles back in and correcting wheelhop first in the suspension, and then fixing the diff problems)
anyways, im open to anything right now...please share what you would do
