Need rear end/driven clutch help

[KoogarKiller]

I am running a H12 Electric ezgo rear end on my current build... It has a gas ezgo secondary splined onto it. The rear end is stamped 12-28-88 if that helps.

I dont know how the secondary clutch made its way onto the rear end as it was on a golf cart I bought with a 440 Snow Mo motor in it.

My question is: What's up with the splines?? I thought I read the older 76-86 ezgo clutches were 10 spline... Is this the same? Is all the ezgo stuff (gas and elect) splined like this??

I have a Comet 102-C on the 440 Twin 2 stroke in my golf cart and am looking for a driven clutch that will take a bigger belt. I think the older ezgos take a 1 3/16" belt ... Can I spline that older model driven clutch onto the electric rear end without issue? I think the 1 3/16" belt would still work ok on the drive clutch. I found an aftermarket one from Comet for $220, but comet is out of business so no help there... Im in AZ so Snowmobiles are not my thing.
