Hey sepe, Nice Hyundai
.... To start with, If its mechanically sound? Try to keep it that way. If you can find someone with ANY stock Hyundai parts and you're into keeping the cart, stock, buy them. If you can't find 'em? ...... Make 'em
Welcome to BuggiesGoneWild
The Hyundai and the Yammie G2-9 parts are so close to being the same its ridiculous. So, you can get the lift kit from either of these units and pretty much bolt them on or you can fabricate your own. The rest of the cart's mods are going to depend on how much ruffage($$) you'd like to drop into your cart, and whether or not you like to tinker..... do things for yourself. Beware Now, these things are highly addictive. You'll find yourself buying 3,or 4 or 5 of them, lol.
Check out all of the posts you can, and I'll bet you'll find the top you want on one cart ..... the lift on another, and different ideas that you just gotta try on other ones.
For me it was hard getting anyone outside of BGW to even be able to tell you what MIGHT fit what. There are quite a few knowledgeable folks in here. and they don't mind having ideas bounced off of them occasionally. The terms boat-anchor, lawn ornament and POS will be used by some don't let it bother you .......... have fun with it.
