I have to order a new clutch

[MOXY100]

I have to order a new clutch for my68 RT, the engine is a 1970,and  its a 440.  I'm wondering if theres a common size for that year and size. I'm not doing the work myself and I don't want to tie up my friends garage for a week, I know its not allot of info, but any input would be apreacated, also what brand would you recamend, thanks, Moxy...

Do you have the 11" bell housing or the 10-1/2" ?

[MOXY100]

Im not sure, if i find out, is there a size for each one, as you can tell i dont do my own work.

They used an 11" up to 69.

70-up got the so-called 10-1/2". Since you said you have a 70 motor - I wonder if they used the whole 70 set-up?

There should be a casting number on it somewhere - If you find one - that will tell me what you have

Also the 11" were cast iron, the 10-1/2" - Aluminum.

I would order a McLeod , 11" .
You will have either the cast iron bell & 143 tooth flywheel or the Alum bell with a 130 tooth flywheel , both use the same 11" disc in either 23 or 18 spline but the 130 tooth is called a 10.95" not 11" .The fastest way to tell is to stick a magnet to it . The Pressure plate is totally different between the two though , the 10.95 has the Borg & Beck / Long style 3 finger pressure plate which is my preference , the 11" 143 tooth has the 3 finger B&B available . I avoid the diaphragm type clutches , one the disc inverts it can stay there & cause the engine to redline or higher on high RPM shifts , I have had this happen to me personally , luckily I had a rev limiter in the car . I also avoid the smaller 10.5 " disc on the 130 tooth , why not have the extra surface area , the clutch will just last longer with an 11" disc
