The propane carb wont fit! Also I need some wheel spacers!

[us74k5]

So the impco 425 wont bolt up to my edelbrock performer rpm intake manifold. I went to autozone thinking I would just grab one of those adapter plates, too bad all of them were only for going from a holley carb to a edelbrock intake. And not vice versa. Are there different base plates for the 425? Or does anyone have any suggestions? Also I am going to pick up some H1 beadlocks tonight and I believe I need 2" spacers for my front dana 60, is that correct? Anyone know where to get some? Thanks again!

Every square bore to spread bore adapter I've owned, used or seen has worked both ways, you just turn it upside down.

Find an old junk mechanical secondary Holley, rob the baseplate, and bolt the baseplate directly to the bottom of the 425. Then it will fit.
