HydroBoost again

[PbFut]

The fire cooked my booster, so i thought i may as well convert as it is likely a new bullet is in the cards and vacuum will be questionable. Lots of threads on the subject but many are junk yard conversions. So Cal is limited on junk yards and most key parts are gone within hours. So I need to pay for a kit. I see ebay kits in the 225 range up to close to a grand. I find most of the higher price kits are often nothing more than a name embossed on the same parts in the lesser priced kits. Has anyone had success with these ebay kits? Can you share if any firewall mods were needed. I don't need feedback on the pv valve. Just the over all kits. I would like to stay under 350 not including the hoses and fittings. Thanks for help
