help with SSI install

[twobone]

I'm swapping my engine - out goes my 81'SC and in goes an 79' SC engine.

I currently have thick flange SSIs installed on the 81'.

Can I use the thicker flange SSIs on the 79 motor? Are there longer bolts and spacers that I can get?

I don't want to have to lose big bucks buying new SSIs and selling my existing set.

Thanks

I 'think' all you will need are the longer exhaust studs from the thick flange engines ('80 on up?)
