T-140 vs TR7RV

Need some compatibility help Brit guys.
Are there any differences in the cases between a '73 T-140 V and a '73 TR7RV?
Jumped the gun with out doing the research and scored a set of TR7RV cases cheap. Date code.. CH = March '73. right? right-side shift .Planed on using them with the innards of the T-140 if it will work. If not I guess these will be cases for my next build. Would appreciate any help. Thanks
