Need Special Carb Intake Boots for Indy 500

[kitakojo]

Hello, need some help.
I recently bought a very nice low mileage 95 Indy 500, minus the carbed engine at a local area auction this fall.
I than purchased on line an engine out of a 92 SP500 which is an EFI engine and also purchased carbs and carb intake boots from a 95 Indy 500.
Recieved the boots in the mail and they do not fit the machined intake side of the engine. The mounting bolt holes on the intake side of the SP500 engine are 2 7/8" apart from center to center and the mounting holes from the 95 Indy boots are roughly 2 1/2" center to center. So this also changes the shape of the boot making it longer in length.
Who knows what make and model sled carb boots will fit the 95 Indy carbs and work on the machined intake surface of the 92 SP500 EFI engine?
I'm trying to build this sled for this season of snowmobile riding.

Thanks for your help.

91-92 indy 650 carb boots fit perfect but they are discontinued and very hard to find.

Boots from a 1980 Yamaha SRX will work to
part# 8G8-13555-01-00
$48 each,might be able to find some aftermarket kimpex ones for cheaper.
