Quick time with Jerico on a B/RB

Which input shaft length do you have on your DR-4 Mopar,Chevy, or Ford? They make all 3 in in the 18 spline Mopar, the length, bearing retainer and pilot bearing dimensions are different. If I remember correctly Quicktimes bell for Mopars for the Jerico is for the Chevy input shaft length. If you are use the Mopar input shaft length and bearing retainer then you have to use the bellhousing for the 833. I used the Quicktime bell for the stock 833 on my small block. 3 out of the 4 bolt holes for the Jerico are already drilled and tapped in that bellhousing, two 1/2 inch holes on top and one 7/16 on the bottom left. I just drilled and tapped another 7/16 hole for the lower right position and used the centering ring that came with the bell on the Mopar bearing retainer and stock Mopar pilot bushing 3/4 inch inside diameter. The 833 bell is deeper so you can use the stock Mopar throwout bearing gives more room for the centrifugal weights to swing out if you use a Soft-Loc Clutch. I ended up using two block plates(cut the center out of one) to get more clearance for the centrifugal weights, with just one the weights just polished the paint on the inside of the bell, two no more witness marks.
