What size bolts are used for the runners on the plenem and lower base. I need to know how many of each size. Thread size and length. Thanks guys.

 

Does anybody know?

 

They are a standard 8mm bolt. Lenghts vary and I think there are 10 bolts for each side.

I believe that TPI Parts sells a complete set.

 

Can someone tell me how long they are and how many of each length I will need.

I'll give you the answer tomorrow, gotta dig the set I bought out. I got them from a guy in WA for $50, chrome allen heads, I couldnt get them cheaper at the HW store. There are 2 or 3 sizes (legnths) I have a set of stockers I'd give you if you paid the postage.

 

The runner bolts are M8X1.5 is the size. I dont quite remember the lengths tho. I know the upper bolts are 2- 30mm long and 2- 40mm long per side if I remember correctly. Hope that helps some

I just did the base on my 87 TPI car and they were NOT metric. I had to get a set of standard allen head bolts to get it to mount. The runner bolts were metric, I just took a stock bolt and found a nut that fit it, then found the right length regular hex head bolts to replace the stockers.

 

The bolts holding the intake base to the heads are 3/8-16,various lengths.
