Of the people that still make adapter plates, who makes the plates with the upper holes siamezed so a single offset bolt goes through the adapter plate to both engine and transmission?I'm looking to remake the steel plate I made along time ago.Tired of having to drill out the holes on the engine.So I'm looking for some of the offset bolts...

Does anyone still make an aluminum adapter plate with the top holes milled out?I got to thinking how heavy my steel adapter plate is,and everything could always weigh a little less...

4 or 5 threads in steel is plenty....

 

in aluminium it's not enough.  That's why the factory threads in the EJ block are nearly an inch deep. 

 

you don't want just a couple threads of aluminum holding your engine and trans toghether.

 

If I were to run an aluminuim plate, it would be with siamesed bolts.....you're on the right track Uberoo.  I would not trust on;y 1/2" of M8 threads.

Scott, your adapter has been working for me like that for years.

 

Thanks... Jeff

 

thats a great report thanks

 

pitch stoper, ok so can some one post a pitcher of the top to bolts, and how thick of a plate do you use for the adaptor .

 

the adapter is the stock bracket from a EA82 trans or 1/8 thick angle Iron would work

No need for any tabs on adapter plate.  EJ bracket bolts to EA 5spd.  I suppose with a 4spd maybe woudl be needed.
